So this question asks, What is entropy or H of a chemical reaction? And so H is the sum of internal energy of a system e plus the product of pressure and volume. Cool. And so how this differs from energy is that it includes this pressure volume term, while also including the energy and so energy by itself does not include this pressure volume. But entropy does include that. And so that's what entropy is, and those are the differences.
