P4-8 (a), (b), (c) P4-88 The gas-phase reaction Ng+H, NH is to be carried out isothermally first in a flow reactor. The molar feed is 50% H, and 50% N.,, at a pressure of 16.4 atm and at a temperature of 227C. (a) Construct a complete stoichiometric table. (b) Express the concentrations in mol/dm3 of each for the reacting species as a function of conversion. Evaluate Cao, 8, and e, and then calculate the concentrations of ammonia and hydrogen when the conversion of H, is 60%. (Ans: CH = 0.1 mol/dm3) (c) Suppose by chance the reaction is elementary with kn, = 400m2/mol/s. Write the rate of reaction solely as a function of conversion for (1) a flow reactor and for (2) a constant-volume batch reactor
