Question

Quizplus · Accepted Answer

Diffusion leads to an increase in entropy. The driving force behind spontaneous processes is the second law of thermodynamics, which dictates that systems tend towards a state of higher entropy (disorder). Diffusion spreads particles out, increasing their distribution and decreasing their organization, thus increasing entropy.
