Analyzing +4 | -1

Consider the following reactions:

I.

{AB}_2(\mathrm{g})+1 / 2 \, {B}_2(\mathrm{g}) \rightleftharpoons {AB}_3(\mathrm{g})

II.

2 {AB}_3(\mathrm{g}) \rightleftharpoons 2 {AB}_2+{B}_2(\mathrm{g})

{K}_1

and

{K}_2

are equilibrium constants of reactions I and II, then the relation between

{K}_1

and

{K}_2

View answer and explanation

Correct option: B

{K}_2 {K}_1^2=1

Option B (

{K}_2 {K}_1^2=1

) is correct because the second reaction is the reverse of the first reaction multiplied by 2, thus affecting the equilibrium constant.
