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)\mathrm { N } _ { 2 ( \mathrm {~g} ) } + 3 \mathrm { H } _ { 2 ( \mathrm {~g} ) } 2NH3( g)2 \mathrm { NH } _ { 3 ( \mathrm {~g} ) }

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

A

K will remain same.

B

K will decrease.

C

K will increase.

D

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

Answer

K will remain same.

Explanation

Solution

: Equlibrium constant (K) is temperature dependent as temperature is constant thus, K will remain same.
