1. When energy available is greater than the energy needed to break bonds or in other words, the energy created from new bonds is greater than the energy needed to
break the origini bonds bonds, the chemical reaction:
absorbs energy
releases energy

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.
