Given information
The given reaction is,
Step-by-step explanation
Step 1.
The given reaction is,
The enthalpy change of the above reaction is .
The entropy of gas is more than that of liquid or solid. If the number of gaseous particle on the product side is greater than that the change of entropy is possibly positive on the reactant side.
The number of gaseous particle in the product side is 2, while that on the reactant side is also 2. But the gas particles on the reactant side are not equivalent and for that, they are more disordered than that of the product that is equivalent molecules of gases. Therefore, the entropy of the product is less than that of the reactant.
Thus, the entropy of the system is negative.
