The standard entropy change, $\triangle_{T} S_{298}^{∘}$ is: - 198.7 J K^-1 mol^-1, for the following reaction: N₂ (g) + 3 H₂ (g) → 2 NH₃ (g) This violates the Second Law of thermodynamics.

Question

Quizplus · Accepted Answer

The given standard entropy change for the reaction is negative, which means that the disorder of the system decreases during the reaction. However, this does not violate the Second Law of thermodynamics, which states that the entropy of a closed system cannot decrease over time. The Second Law only requires that the total entropy of the system and its surroundings must increase during any spontaneous process, which may or may not be the case for this specific reaction. Therefore, the statement is false.
