Ammonia under a pressure of 15 atm at 27°c is heated to 347°c in a closed vessel in the presence of a catalyst. under the conditions, nh3 is partially decompose

Ammonia under a pressure of 15 atm at 27°C is heated to 347°C in a closed vessel in the presence of a catalyst. Under the conditions, NH3 is partially decomposed according to the equation, 2NH3 N2 +3H2 the vessel is such that the volume remains effectively constant where as pressure increases to 50 atm. Calculate the percentage of NH actually decomposed: (a) 65% (b) 61.3%6 (c) 62.5% (d) 64% 252/554
