What is equilibrium expression for the reaction,

{P_4}(s) + 5{O_2}(g)\leftrightharpoons{P_4}{O_{10}}(s)\,\,?

View answer and explanation

Correct option: B

{K_c} = \frac{1}{{{{\left[ {{O_2}} \right]}^5}}}

Option B (

{K_c} = \frac{1}{{{{\left[ {{O_2}} \right]}^5}}}

) is correct because solids are not included in the equilibrium expression.
