Question

Given the following reaction at equilibrium $N_2\left(g\right)+3H_2\left(g\right)\rightleftharpoons 2N{H}_3\left(g\right)$. Some inert gas is added at constant volume. Predict which of the following facts will be affected?

• A. More of $N{H}_3\left(g\right)$ is produced
• B. Less of $N{H}_3\left(g\right)$ is produced
• C. No effect on the degree of advancement of the reaction at equilibrium
• D. $K_p$ of the reaction is increased

Answer 1

The correct option is B

Less of $N{H}_3\left(g\right)$ is produced

The addition of an inert gas at constant volume does not affect equilibrium.
