Description
Indicate how entropy of the system changes for each of the physical processes shown below.either decrease in entropy and decrease entropy.
crystallization
condensing
dissolving
diffusion
melting
at 25°C. Assume that G°A = 8748 J/mol and G°B = 11024 J/mol.
Calculate the value of the equilibrium constant for this reaction.
Explanation & Answer
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.
