Question

Determine the entropy change for the reaction  given the following information:

Quizplus · Accepted Answer

The entropy change for the given reaction can be determined using the formula: 
ΔS° = ΣS°(products) - ΣS°(reactants)
Since there is no information given about the products of the reaction, we only use the given value of standard entropy for the reactants. Therefore, 
ΔS° = (233.91 J/K) - (327.81 J/K) = -93.9 J/K
The negative sign indicates that the reaction leads to a decrease in entropy. Now, since the question asks for the entropy change, we write the answer as:
(F1F1F1S1F1F1F1093.9 J/K)
