MCQ
$K_1, K_2$ and $K_3$ are the equilibrium constants of the following reactions $(I), (II)$ and $(III)$, respectively :-
$(I)$ $N_2 + 2O_2 \rightleftharpoons 2NO_2$
$(II)$ $2NO_2 \rightleftharpoons N_2 + 2O_2$
$(III)$ $NO_2 \rightleftharpoons \frac{1}{2}N_2 + O_2$
The correct relation from the following is
$(I)$ $N_2 + 2O_2 \rightleftharpoons 2NO_2$
$(II)$ $2NO_2 \rightleftharpoons N_2 + 2O_2$
$(III)$ $NO_2 \rightleftharpoons \frac{1}{2}N_2 + O_2$
The correct relation from the following is
- A${K_1} = \sqrt {{K_2}} = {K_3}$
- B${K_1} = \frac{1}{{{K_2}}} = \frac{1}{{{K_3}}}$
- C${K_1} = \frac{1}{{{K_2}}} = {K_3}$
- ✓${K_1} = \frac{1}{{{K_2}}} = \frac{1}{{{{({K_3})}^2}}}$
