Consider the following gaseous equilibrium with equilibrium constants

{K_1}

and

{K_2}

respectively

\begin{array}{l} S{O_2}(g) + \frac{1}{2}{O_2}(g)\underset{{}}{\overset{{}}{\leftrightharpoons}}S{O_3}(g)\\ 2S{O_3}(g)\underset{{}}{\overset{{}}{\leftrightharpoons}}2S{O_2}(g) + {O_2}(g) \end{array}

The equilibrium constants are related as

View answer and explanation

Correct option: A

K_1^2 = \frac{1}{{{K_2}}}

Option A (

K_1^2 = \frac{1}{{{K_2}}}

) is correct because the second reaction is the reverse of the first reaction multiplied by 2, so the equilibrium constant is the inverse square of the first reaction's equilibrium constant.
