(a)
Interpretation:
For the reaction
Concept Introduction:
Le Chatelier’s principle:
If some forces applied, the system at equilibrium will get disrupted. This change in equilibrium can be due to the change in pressure or temperature. The change in reactant concentration can also disrupt the equilibrium. Over time, the forward and backward reaction become equal and will attain a new equilibrium. The equilibrium will shifts to right, if more products are formed and the system will shifts to left, if more reactants are formed.
The principle states that if some stress is applied to the system at equilibrium, the system will adjust itself in a direction which reduces the stress.
