Explanation:
Entropy is the measure of randomness or disorder of a system. If a system moves from an ordered arrangement to a disordered arrangement, the entropy is said to decrease and vice versa.
For the reaction 
In this reaction gaseous reactants are converting to solid products. The randomness will decrease and hence entropy will also decrease. Thus is negative or less than zero.
Among solids, liquids, and gases, solids generally have the highest entropy because solid particles are the least mobile, and entropy is inversely related to mobility of particles.
