Question

how increased temperature affects the rate of diffusion​

Answer 1

Answer:

Higher temperatures increase the energy and therefore the movement of the molecules, increasing the rate of diffusion. Lower temperatures decrease the energy of the molecules, thus decreasing the rate of diffusion.

Answer 2

Answer:

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 the concentration difference still have to be large in order for the effect to be easily seen. If the two concentration 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
