Q. For the system; $3A + 2B \rightleftharpoons C,$ the expression for equilibrium constant is
A) $\frac{\lbrack A\rbrack^{3}\lbrack B\rbrack^{2}}{\lbrack C\rbrack}$
B) $\frac{\lbrack C\rbrack}{\lbrack A\rbrack^{3}\lbrack B\rbrack^{2}}$
C) $\frac{\lbrack 3A\rbrack\lbrack 2B\rbrack}{\lbrack C\rbrack}$
D) $\frac{\lbrack C\rbrack}{\lbrack 3A\rbrack\lbrack 2B\rbrack}$
Explanation
(b)
Equilibrium constant for the reaction,
$3A + 2B \rightleftharpoons C,$ is
$K = \frac{\lbrack C\rbrack}{\lbrack A\rbrack^{3}\lbrack B\rbrack^{2}}$
