Ammonia under...

Question

Ammonia under pressure of $15$ atm at $27^{o}$ C is heated to $347^{o}$ C in a closed vessel in the presence of catalyst. Under the conditions, $N H_{3}$ is partially decomposed according to the equation, $2 N H_{3} ⇌ N_{2} + 3 H_{2}$ . The vessel is such that the volume remains effectively constant whereas pressure increases to $50$ atm. Calculate the percentage of actually decomposed.
