The entropy change will be negative because the number of particles in the system decreased from left to right.
The term entropy refers to the degree of disorder in a system. We know that the production of gases would lead to an increase in the entropy of the system.
Now given the equation; N₂ (g) + 3H₂ (g) --> 2NH₃ (g), the entropy change will be negative because the number of particles in the system decreased from left to right.
