Solution

The correct option is D Both assertion and reason are correct but reason is not correct explanation of assertion.
$2 O_{3} \to 3 O_{2}$
i.e., 2 mol $O_{3}$ = 3 mol $O_{2}$ = $3 \times 4 e q . O_{2}$
So, 1 mol of $O_{3}$ on decomposition gives $\frac{3}{2}$ mol of $O_{2}$
Also, $E_{O_{3}} = \frac{M}{6} = \frac{48}{6} = 8 g . {e q}^{- 1}$
