For the reaction N₂(g) + 3H₂(g) ⇌ 2NH₃(g), what happens if the concentration of N₂ is increased?
The equilibrium shifts to the right
The equilibrium shifts to the left
The value of the equilibrium constant (Kc) increases
The reaction rate decreases
📝 Detailed explanation
According to Le Chatelier’s principle, increasing the concentration of a reactant causes the system to shift towards the products (right) to consume the excess reactant.
