Solution

The correct option is B 1.0 mole of $S O_{3}$ will be produced
Finding the limiting reagent:
$S O_{2} = \frac{given moles}{Stoichiometric coefficient} = \frac{1}{2} = 0.5 O_{2} = \frac{given moles}{stoichiometric coefficient} = \frac{1}{1} = 1$
Therefore, $S O_{2}$ will be the limiting reagent.
Amount of $O_{2}$ consumed = $0.5 mole$
Amount of $S O_{3}$ produced = $1 mole$
