MCQ

The compound $A$ and $B$ are mixed in equimolar proportion to form the products, $A + B$ $\rightleftharpoons$ $C + D$. At equilibrium, one third of $A$ and $B$ are consumed. The equilibrium constant for the reaction is

A
$0.5$
B
$4$
C
$2.5$
✓
$0.25$

✓

Answer

Correct option: D.

$0.25$

(d) $K = \frac{{[C][D]}}{{[A][B]}} = \frac{{\frac{1}{3} \times \frac{1}{3}}}{{\frac{2}{3} \times \frac{2}{3}}} = \frac{1}{4} = 0.25$

So, $K = 0.25$
