The speed of a molecule is proportional to the square root of the absolute temperature and temperature is the measure of the average kinetic energy of molecules in an object, therefore when the temperature increases the molecules will have more kinetic energy, so they move faster and due to more spontaneous spreading ...
Why is diffusion faster on heating?
The rate of diffusion increases with the increase of temperature because the kinetic energy of particles increases due to a rise in temperature. Hence particles move and spread out faster. Therefore, on heating diffusion becomes faster.
What is diffusion Why does rate of diffusion become faster with the increases temperature?
Diffusion is directly proportional to Kinetic energy and with increase in temperature kinetic energy increases . Answer: At higher temperatures the Kinetic energy increases which directly proportional to diffusion. Hence at high temperatures the diffusion becomes faster.
How does rate of diffusion vary with temperature?
Explanation: Increasing the temperature increases the kinetic energy of the molecules, which leads them to moving faster and more frequently, and thus increasing the rate of diffusion.
What is the effect of the following on the rate of diffusion temperature and density of liquid?
Diffusion is directly proportional to temperature as it increases the kinetic energy of the molecules and inversely proportional to density of the substance. On increasing the temperature, the diffusion increases and on increasing the density of substance, the diffusion decreases and vice versa.

What is the effect of temperature on rate of diffusion of liquids Why?
When temperature increases, the kinetic energy of the particles has increased. The increased motion of the particles causes them to diffuse faster. Therefore, at higher temperatures, the rate at which fluid particles will diffuse is faster than at lower temperatures.
What would be the effect of temperature?
An increase in the temperature of a system favors the direction of the reaction that absorbs heat, the endothermic direction. Absorption of heat in this case is a relief of the stress provided by the temperature increase. For the Haber-Bosch process, an increase in temperature favors the reverse reaction.
In which situation diffusion takes place faster?
Diffusion in gases is quick because the particles in a gas move quickly. It happens even faster in hot gases because the particles of gas move faster.
Does diffusion depend on temperature?
Temperature and the rate of diffusion have a directly proportional relationship with one another. The rate of diffusion increases as the temperature increases. At higher temperatures, particles move faster because more energy is available to diffuse them.
Does rate of diffusion depend on temperature?
As from the above it is clear that the rate of diffusion depends upon the temperature, hence the rate of diffusion is faster in gas as in higher temperature gases molecules have high kinetic energy.
What are the 5 factors that affect diffusion?
Several factors affect the rate of diffusion of a solute including the mass of the solute, the temperature of the environment, the solvent density, and the distance traveled.
Which of the following will have the slowest rate of diffusion at a given temperature?
Chlorine is the slowest. We must assume that all these gases are at the same temperature.
Why does kinetic energy increases with temperature?
As the temperature of the gas increases, the particles gain kinetic energy and their speed increases. This means that the particles hit off the sides more often and with greater force.
Which way do particles move in diffusion?
Diffusion happens when the particles are free to move. This is true in gases and for particles dissolved in solutions - but diffusion does not occur in solids. Particles diffuse down a concentration gradient, from an area of high concentration to an area of low concentration.
What are 2 examples of diffusion?
- The smell of perfumes/Incense Sticks.
- Opening the Soda/Cold Drinks bottle and the CO2 diffuses in the air.
- Dipping the tea bags in hot water will diffuse the tea in hot water.
- Small dust particles or smoke diffuse into the air and cause air pollution.
What happens to particles when they are heated?
When an object is heated the motion of the particles increases as the particles become more energetic. If it is cooled the motion of the particles decreases as they lose energy.
What does not affect the rate of diffusion?
Complete answer: The electrical charges of the diffusion particles are the only factor that does not have an effect on the rate at which diffusion occurs.
What affects diffusion rate?
The greater the difference in concentration, the quicker the rate of diffusion. The higher the temperature, the more kinetic energy the particles will have, so they will move and mix more quickly. The greater the surface area, the faster the rate of diffusion.
Does diffusion depend on pressure?
Diffusion is the spontaneous movement of molecules from one region to another due to temperature, pressure, concentration, or other force gradients. ... It is dependent on the temperature and pressure. The pressure dependence is negligible up to about 20 bar.
Why does diffusion occur?
Diffusion is the process by which particles of one substance spread out through the particles of another substance. ... Diffusion happens on its own when the particles spread out from an area of high concentration , where there are many of them, to areas of low concentration where there are fewer of them.
Which type of diffusion is very very slow?
The diffusion of a solid in another solid is a very slow process because the particles in solids can not move from their positions. the particles can show a little vibrations about their fixed position. due to lack of sufficient movements in particles of solids,the diffusion of solids in solids is a slow process.
Why diffusion takes place faster in gas than liquid?
The molecules of gas have more kinetic energy than liquid molecules and are smaller. ... The distance between the constituent particles in gases becomes greater than in liquids, resulting in diffusion faster in gases than in liquids.
What is the effect of temperature on chemisorption?
Chemisorption increases with an increase in temperature upto a certain limit and then after that, it starts decreasing as further high temperature helps in breaking the bonds between the absorbed molecules and the adsorbate.
Does heat of reaction change with temperature?
In general, enthalpy of any substance increases with temperature, which means both the products and the reactants' enthalpies increase. The overall enthalpy of the reaction will change if the increase in the enthalpy of products and reactants is different.
What is the effect of temperature on heat of reaction?
Answer: When the temperature of a system increases, the kinetic and potential energies of the atoms and molecules in the system increase. Thus, the internal energy of the system increases, which means that the enthalpy of the system increases – this is true under constant pressure or constant volume.
