Analyzing +4 | -1

K_1, K_2

and

K_3

are the equilibrium constants of the following reactions (I), (II) and (III) respectively:

(I)

{N}_2+2 {O}_2 \rightleftharpoons 2 {NO}_2

(II)

2 {NO}_2 \rightleftharpoons {N}_2+2 {O}_2

(III)

{NO}_2 \rightleftharpoons \frac{1}{2} {~N}_2+{O}_2

The correct relation from the following is

View answer and explanation

Correct option: B

K_1=\frac{1}{K_2}=\frac{1}{\left(K_3\right)^2}

Option B (

K_1=\frac{1}{K_2}=\frac{1}{\left(K_3\right)^2}

) is correct because it accurately reflects the relationships between the equilibrium constants for the given reactions based on reversing and scaling the reactions.
