1. We are planning to operate a PFR to convert A into R. This is a liquid reaction. The concentration and rate of reaction are given below. What size of PFR would be needed for 80% conversion of a feed stream of 1000 mol A/h at Cao= 1.5 mol/liter? AR Show the PFR volume equivalent in Levenspiel plot drawn in excel, and calculate the volume by using Simpson's method. Show the calculations, do not copy from the solution manual.

The gas-phase reaction 0.5N2 + 1.5H2 NH3 Is to be carried out isothermally. The molar feed is 50% H2 and 50% N2, at a pressure of 16.4 atm and 227C. a) Construct a complete stoichiometric table. b) What are Cao, 8, ? Calculate the concentrations of ammonia and hydrogen when the conversion of H2 is 60%. c) Suppose by chance the reaction is elementary with kn2=40 dm/mol/s. Write the rate of reaction solely as a function of conversion for a flow system and a a constant volume batch system
