Answer to Question #243471 in Chemistry for deevika

Question

The container where the following reaction is occurring (at equilibrium) has its volume suddenly increased. Which way will the equilibrium shift to compensate this change?

N2 (g) + 3H2 (g) ⇌2NH3 (g) ∆H = -92 kJ/mol

Answer 1

Increased volume means decreased pressure. Therefore, the equilibrium will shift towards the greater amount (moles) of reactants. For this equation, the equilibrium will shift to the left.
