Q. For the reaction $2HI_{(g)} \rightleftharpoons H_{2(g)} + I_ {2(g)} -Q\, KJ$ , the equilibrium constant depends upon

IIT JEEIIT JEE 1981Equilibrium

Solution:

$2 HI (g) \rightleftharpoons H _{2}(g)+ I _{2}(g)-Q \,kJ $

$\Delta n_{g}=n_{P}-n_{R}=2-2=0$

As the number of moles of products and reactants are equal, so equilibrium constant is not affected by any change in pressure and volume. Catalyst also does not affect the equilibrium constant. It is an endothermic reaction, hence equilibrium constant depends only upon the temperature.
