Q. In which of the following reactions, the value of $K_{p}$ will be equal to $K_{c}$?
A) $PCl_{5} \rightleftharpoons PCl_{3} + Cl_{2}$
B) $2NH_{3} \rightleftharpoons N_{2} + 3H_{2}$
C) $H_{2} + I_{2} \rightleftharpoons 2HI$
D) $2SO_{2} + O_{2} \rightleftharpoons 2SO_{3}$
Explanation
(c)
If $n_{P} = n_{R},$ then $K_{p} = K_{c}$
where, $n_{p} =$ number of moles of products
$n_{R} =$ number of moles of reactants
