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 10, while that on the reactant side is 9. So, the number of gaseous particle in the product side is greater than that on the reactant side. Therefore, the entropy of the product is greater than that of the reactant.

Thus, the entropy of the system is positive.
