For the reaction,

{\mathrm{N}_2}{\mathrm{O}_5} \to 2\mathrm{N}{\mathrm{O}_2} + \frac{1}{2}{\mathrm{O}_2}

Given,

- \frac{{d\left[ {{\mathrm{N}_2}{\mathrm{O}_5}} \right]}}{{dt}} = {K_1}\left[ {{\mathrm{N}_2}{\mathrm{O}_5}} \right]

\frac{{d\left[ {\mathrm{N}{\mathrm{O}_2}} \right]}}{{dt}} = {K_2}\left[ {{\mathrm{N}_2}{\mathrm{O}_5}} \right]

\mathrm{and}\;\;\frac{{d\left[ {{\mathrm{O}_2}} \right]}}{{dt}} = {K_3}\left[ {{\mathrm{N}_2}{\mathrm{O}_5}} \right]

The relation in between

{K_1},{K_2}\;and\;{K_3}

is:

View answer and explanation

Correct option: A

2{K_1} = {K_2} = 4{K_3}

Option A (

2{K_1} = {K_2} = 4{K_3}

) is correct because it correctly relates the rate constants based on the stoichiometry of the reaction.
