Problem 4. The gas-phase reaction 21N2+23H2NH3 is to be carried out isothermally first in a flow reactor. The molar feed is 50%H2 and 50%N2, at a pressure of 16.4atm 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 CA0,, and , and then calculate the concentrations of ammonia and hydrogen when the conversion of H2 is 60%. (Ans.: CH2=0.1mol/dm3 ) (c) Suppose by chance the reaction is efementary with kN2=40dm3/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
