What is the most important factor in explaining why diffusion occurs spontaneously?

Question

Quizplus · Accepted Answer

Diffusion is a spontaneous process because it leads to an increase in entropy, which is a measure of disorder or randomness. When particles diffuse, they move from an area of high concentration to an area of low concentration, which increases the overall randomness or disorder of the system. This is because the particles become more evenly distributed, and there are more ways for them to be arranged in the new, more dispersed state. Therefore, the most important factor in explaining why diffusion occurs spontaneously is the increase in entropy.
