Solution

The correct option is B $187$
$S O_{2} + \frac{1}{2} O_{2} ⇋ S O_{3}$
0.3 0.2 0 ------- initial
0.3-0.2 0.2-0.1 0.2 ---- --- final
=0.1 =0.1

$Mole fraction of a component=moles of that componenttotal number of moles$

$Mole fraction of SO2=0.10.1+0.1+0.2=0.10.4=0.25$

$Partial pressure of SO2=mole fraction of SO2×total pressure$

$Partial pressure of S O_{2} = 0.25 \times 750 t o r r = 187 t o r r$
