For the reaction, N 2 ( g ) + 3 H 2 ( g ) ⇌ 2 N H 3 ( g ) ; Δ H ° = - v e the number of moles of H 2 at equilibrium will increase when

Options

  1. Avolume of vessel is increased
  2. Bvolume of vessel is decreased
  3. CNe gas is added at constant volume
  4. DN H 3 is removed

Correct answer

A. volume of vessel is increased

Step-by-step solution

For the reaction, N 2 ( g ) + 3 H 2 ( g ) ⇌ 2 N H 3 ( g ) ; Δ H ° = - v e the number of moles of H 2 at equilibrium will increase when volume of vessel is increased. Equilibrium will shift in backward direction when volume is increased, thus number of moles of H 2 will increase.
