Q. In which of the following reactions, the concentration of product is higher than the concentration of reactant at equilibrium? $(K = equilibrium\ constant)$
A) $A \rightleftharpoons B;K = 0.001$
B) $M \rightleftharpoons N;K = 10$
C) $X \rightleftharpoons Y;K = 0.005$
D) $R \rightleftharpoons P;K = 0.01$
Explanation
(b)
For a reaction, $K_{c} = \frac{\lbrack product\rbrack}{\lbrack reactant\rbrack}$
Hence,
if $K_{c} > 1$, then [Product]>[Reactant]
