What happens during a redox reaction? Cations interchange their positions in two compounds.
Anions interchange their positions in two compounds.
Some atoms gain electrons and some lose electrons.
All atoms gain a fixed number of electrons.

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.
