Given information
The given reaction is
Step-by-step explanation
Step 1.
The entropy of gas is more than that of liquid or solid. The change of entropy is possibly positive if the number of gaseous particle on the product side is greater than that on the reactant side.
The number of gaseous particle in the product side is two, while that on the reactant side is one. Hence, the number of gaseous particle in the product side is more than that on the reactant side. Therefore, the entropy of the product is greater than that of the reactant.
Thus, the entropy of the given reaction is positive.
