For the reactions

\mathrm{I}_2(\mathrm{aq}) \rightleftharpoons \mathrm{I}_2

(oil) Equilibrium constant is

\mathrm{K}_1

\mathrm{I}_2

(oil)

\rightleftharpoons \mathrm{I}_2

(ether) Equilibrium constant is

\mathrm{K}_2

for the reaction

\mathrm{I}_2(\mathrm{aq}) \rightleftharpoons \mathrm{I}_2

(ether) Equilibrium constant is

\mathrm{K}_3

The relation between

\mathrm{K}_1, \mathrm{K}_2, \mathrm{K}_3

View answer and explanation

Correct option: B

\mathrm{K}_3=\mathrm{K}_1 \mathrm{~K}_2

Option B (

\mathrm{K}_3=\mathrm{K}_1 \mathrm{~K}_2

) is correct because when adding reactions, the equilibrium constants are multiplied.
