WebJan 1, 2024 · The entropy of our system has increased, because we have relaxed a constraint and allowed more microstates into our system. Most of these final states look disordered. Diffusion is therefore an entropically favorable process that brings an ordered system into a disordered one. Additional remark.

WebMay 8, 2024 · This condition describes an endothermic process that involves a decrease in system entropy. In this case, ΔG will be positive regardless of the temperature. Such a process is nonspontaneous at all temperatures. ΔH is negative and ΔS is positive. This condition describes an exothermic process that involves an increase in system entropy. Web8.4. Nonnegativity of Relative Entropy In these examples, the relative entropy has always been nonnegative.
