ANSWER:

Step 1 of 4

(a) :

On the reactant side, there are no gaseous molecules. On the product side, there is one gaseous molecule. The gaseous molecules have the maximum number of microstates than all other states of matter. Thus, the sign of entropy change for this reaction is positive as there is a gaseous substance on the product side.
