Solution

The correct option is A $5.6$ lit
Equivalents of $H_{2} O_{2}$ needed to react completely
$\begin{matrix} with 0.1 mole k M n O_{4} & = 0.1 \times n f (n_{f} o f k M n O 4 = 5) = 0.5 \end{matrix}$
$\begin{matrix} Now, H_{2} O_{2} ⟶ H_{2} O + 1 / 2 O_{2} 1 equivalent H_{2} O_{2} produce \frac{22 \cdot 4}{2} = 11 \cdot 2 L O_{2} 0. 5 equivalent H_{2} O_{2} will produce 0.5 \times 11 \cdot 2 = 5.6 {L O}_{2} So, A) 5.6 litre is correct answer. \end{matrix}$
