Why does temperature affect the rate of diffusion?

1) As the temperature increases, more particles gain kinetic energy

2) Particles move faster and thus move randomly from a region of higher concentration to a region of lower concentration at an increased rate

Higher temperatures increase the kinetic energy of the particle .Therefore the particles are more likely to colide and move from the area of high concentration to the lower concentrated area.

Hi,

Diffusion is all about the movement of particles, so with an increase in temperature particles have more kinetic energy which means they will move faster from an area of high concentration to low concentration.
