Interpretation:
The sign of the entropy change of the system and the surrounding and the spontaneity of the given reaction at all temperatures is to be predicted.
Concept introduction:The entropy of gas is more than that of liquid or solid. The change of entropy of the reaction is possibly positive if the number of gaseous particle on the product side is greater than that on the reactant side.
The entropy of the surrounding is calculated by the formula,
The total entropy change of the universe should be positive for the reaction to be spontaneous.
The entropy change of the universe is the sum of the entropy change of the system and the surrounding.
To determineThe sign of the entropy change of the system and the surrounding and the spontaneity of the given reaction at all temperatures.
