Solution

The correct option is A P/3
$\begin{matrix} N_{2} + & 3 H_{2} & ⇌ & 2 N H_{3} I n i t i a l l y & 1 & 3 & 0 A t e q u i l i b r i u m & 1 - 0.5 & 3 - 1.5 & 2 \times 0.5 T o t a l m o l e s & = (1 - 0.5) + (3 - 1.5) + 1 = 3 \end{matrix}$
$P_{N H_{3}} = \frac{m o l e s o f N H_{3}}{t o t a l n o . o f m o l e s} (P)$
$P_{N H_{3}} = \frac{1}{3} P$
