Entropy is a measure of disorder. As a general rule. when objects lose heat, they become more ordered (their entropy goes down). When they gain heat, they become less ordered (their entropy goes up). Also, when objects do things like dissolve, the they become more disordered. So, here are the answers: Crystallization: Entropy Decreases Condensing: Entropy Decreases Dissolving: Entropy Increases Diffusion: Entropy Increases Melting: Entropy Increases. I assume the last statement about equilibrium constant is not part of your question. Hope this helps.
