Solution

The correct option is C 5.6 L
$E q o f A l = e q o f H_{2}$
$\frac{4.5}{\frac{27}{3}} = e q o f H_{2}; \frac{4.5}{9} = e q o f H_{2}$
$2 H^{+} + 2 e^{-} \to H_{2}$
eq. of $H_{2}$ = Number of moles $\times n$ factor $0.5 = n_{H_{2}} \times 2$
$V_{H_{2}} = \frac{0.5}{2} \times 22.4; V_{H_{2}} = 5.6 L$
