Simple diffusion occurs naturally as it ___ of a system.

Question

Quizplus · Accepted Answer

Simple diffusion is a passive process that occurs naturally as a result of the random movement of particles; it does not require an input of energy. During simple diffusion, particles move from an area of high concentration (i.e., high potential energy) to an area of low concentration (i.e., low potential energy), which increases the entropy (or disorder) of the system. Therefore, the best choice is D, as decreasing the entropy would actually oppose the process of simple diffusion.
