A certain reaction requires 0.250 moles of Na2SO4. How much sodium sulfate should the chemist weigh out to perform
the reaction?

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.
