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.
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?
(i) K will remain same
(ii) K will decrease
(iii) K will increase
(iv) K will increase initially and decrease when pressure is very high

Ans: Option(i)
The given reaction is :-
N2 (g) + 3H2 (g) ?2NH3 (g)
A/C to vart Hoff's eqn,
=
K is dependent on temperature. As temperature remains constant at equilibrium, so K will remain constant in the given conditions.
