EXPLAINATION :
For this question we need apply the basic idea of Le Chatelier principle , along with this we also know that NH3 is a weak base.
Ammonia is a weak base and the Le Chatelier principle also states that a reaction will proceeds in that direction only where the stress applied on reaction is managed well. So in the RHS, the products are more stable as they are molecule and at the LHS the ions are present so it will be easy to go reaction from LHS to RHS.
