You need to calculate the enthalpy change (AHO) of the reaction A+B — C. How can the enthalpies given for the reaction steps below be combined to
give the overall change in enthalpy?

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.
