Q. The unit of equilibrium constant, $K$ for the reaction, $A + B \rightleftharpoons C$, would be
A) $mol\ L^{- 1}$
B) mol L
C) $L\ mol^{- 1}$
D) Dimensionless
Explanation
(c)
$A + B \rightleftharpoons C$
$K = \frac{\lbrack C\rbrack}{\lbrack A\rbrack\lbrack B\rbrack}$
$= \frac{mol\ L^{- 1}}{mol\ L^{- 1} \times mol\ L^{- 1}} = \left( mol\ L^{- 1} \right)^{- 1} = mol^{- 1}L$
