Question

On addition of an inert gas at constant volume to the reaction
$N_2\left(g\right)+3H_2\left(g\right)\rightleftharpoons 2N{H}_3\left(g\right)$ at equilibrium

• A. The reaction remains unaffected
• B. Forward reaction is favoured
• C. The reaction halts
• D. Backward reaction is favoured

Answer 1

The correct option is A The reaction remains unaffected

Addition of an inert gas of constant volume condition to an equilibrium has no effect hence reaction remains unaffected. This is because addition of inert gases at constant volume increases the total pressure. However it does not have partial pressures of the reactants and products.
