    that will affect it’s rate. The rate of diffusion will vary depending on the size of the particle. For example‚ a smaller particle will move faster than a large molecule at a given temperature . During reactions‚ when there is more energy‚ the reaction will take place at a faster rate. An increase in temperature will result in and increase in the amount of energy available‚ therefore the particle will move faster and the rate of diffusion will increase. Another factor affecting the rate of diffusing
