Solution

The correct option is A $22 / 3$
$A_{2} + 3 B_{2} \to 2 A B_{3}$
$5$ moles $7$ moles

Given: $5$ moles of $A_{2}$ and $7$ moles of $B_{2}$ .

So, it means the $B_{2}$ is limiting reagent.

Total number of moles of gases present in the container at the end of the reaction $= \frac{14}{3}$ moles of $A B_{3}$ + $(5 - \frac{7}{3})$ moles of $A_{2}$ + $(7 - 7)$ moles of $B_{2} = \frac{22}{3} .$
