MCQ
In which of the following reactions, the concentration of the product is higher than the concentration of reactant at equilibrium ? ($K =$ equilibrium constant)
  • A
    $A \rightleftharpoons B;\,K = 0.001$
  • ✓
    $M \rightleftharpoons N;\,K = 10$
  • C
    $X \rightleftharpoons Y;\,K = 0.005$
  • D
    $R \rightleftharpoons P;\,K = 0.01$
✓

Answer

Correct option: B.
$M \rightleftharpoons N;\,K = 10$
b
$K = \frac{{{\text{[Product]}}}}{{{\text{[Reactant]}}}}$

Hence, [Product] $=$ $K$ [Reactant]
$\therefore $ [Product] $ > $ Reactant, when $K > 1$
