Question

On increasing the pressure, in which direction will the gas phase reaction proceed to re-establish equilibrium, is predicted by applying the Le Chatelier’s principle. Consider the reaction.

\[\ce{N2 (g) + 3H2 (g) ⇌ 2NH3 (g)}\]

Which of the following is correct, if the total pressure at which the equilibrium is established, is increased without changing the temperature?

Options

  • K will remain same.

  • K will decrease.

  • K will increase.

  • K will increase initially and decrease when pressure is very high.

Solution

K will remain same.

Explanation:

\[\ce{N2 (g) + 3H2 (g) ⇌ 2NH3 (g)}\]

According to Le Chatelier’s principle, at constant temperature, the equilibrium composition will change but K will remain same.
