Entropy of mixing

Entropy of mixing

In this video, we focus our attention to derive entropy of mixing for ideal gases.

Since the molecules of ideal gases do not interact, we can spilit the mixing of two ideal gases into two events: Expansion of each gas system into the final volume of the mixture. The entropy change accompanied is thus the entropy change with volume. The summation of entropy changes of the constituent ideal gas systems results in the entropy of ideal mixing.
