Solution

The correct option is B
$\frac{2}{3}$ of total pressure

$P_{H_{2}} = \frac{n_{H_{2}}}{n_{H_{2}} + n_{O_{2}}} \times P_{T}$

$\Rightarrow \frac{\frac{3}{2}}{\frac{3}{2} + \frac{24}{32}} \times P_{T}$

$\Rightarrow \frac{1.5}{1.5 + 0.75} P_{T}$

$\Rightarrow \frac{1.5}{2.25} P_{T}$

$\Rightarrow \frac{2}{3} P_{T}$
