Explanation:

At the lowest temperature the gas will have the lowest rate of diffusion because diffusion deals with the motion of particles.

Diffusion is the movement of particles from a region of high concentration to that of a lower concentration. According to the kinetic molecular theory of gases, the temperature of a gas is a measure of the average kinetic energy of the molecules. The higher the temperature faster the molecules diffuse.

The gas with the lowest temperature will be the slowest to diffuse.
