Problem

Two nonpolar organic liquids, hexane (C6H14) and heptane (C7H16), are mixed.

Hexane and heptane are miscible with each other in all proportions. In making a solution of them, is the entropy of the system increased, decreased, or close to zero, compared to the separate pure liquids?

Solution

Recall: Entropy is a measure of energy dispersal or disorder in systems. The formation of solutions is driven by the tendency of a system towards greater entropy.
