Question

The equilibrium constant for the reaction

$A_{2}(g)+B_{2}(g) \rightleftharpoons 2 A B(g)$ is 20 at $500 K$.

The equilibrium constant for the reaction,

$2 AB ( g ) \rightleftharpoons A _{2}( g )+ B _{2}( g )$ at $500 K$ would be :

(A) 20

(B) $0.5$

(C) $0.05$

(D) 10

Answer 1

The equilibrium constant for the reaction —

$2 AB ( g ) \rightleftharpoons A _{2}( g )+ B _{2}( g )$ at $500 K$ would be $0.05$.

So, The correct option of this question is (C).
