Q12 / 180 · COMEDK 2014 · Chemistry

In which of the following case, does the reaction go farthest to completion if

  • Correct answer
    A
    $K_{C}=10^{2}$
  • B
    $K_{C}=10$
  • C
    $K_{C}=10^{-2}$
  • D
    $K_{C}=1$

Solution

Equilibrium constant, $K_{C}=\frac{\text { [Products] }}{\text { [Reactants }]}$ Higher value of $K_{C}$, indicates higher concentration of products which means the reaction goes more towards the completion.

Hence, the correct answer is option: 'A'.
