Which of the following statement is true when equilibrium is established in the reaction?
$A+B \rightleftharpoons C+D, K_C=10$
- $[C][D]=[A][B]$
- $[C]=[A]$ and $[B]=[D]$
- $[A][B]=0.1[C][D]$
- $[A]=[B]=[C]=[D]=10 \mathrm{M}$
Solution
$A+B \rightleftharpoons C+D$
Given, $K_C=10$
$K_C=\frac{[C][D]}{[A][B]}$
$\begin{aligned} & {[A][B]=\frac{1}{K_C}[C][D]} \\ & {[A][B]=\frac{1}{10}[C][D]} \\ & {[A][B]=0.1[C][D]}\end{aligned}$
