Faster rate of diffusion

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.

Note that the concentration difference still has to be large, in order for the effect to be easily seen. If the two concentrations are equal, or isotonic to each other, then an increase in temperature will just increase the velocity of the particles, but the concentration will still be the same on both sides.

So, concentration still plays a major role in diffusion, but increasing the temperature increases the rate of diffusion.
