P8-7 Use the data and reaction in Problem 8-6 for the following exercices. (a) Plot the conversion and temperature of the PFR profiles up to a reactor volume of 10dm3 for the case when the reaction is reversible with KC=10m3/kmol at 450K. Plot the equilibrium conversion profile. (b) Repeat (a) when a heat exchanger is added, Ua=20cal3/m3/s/K, and the coolant temperature is constant at Ta=450K. (c) Repeat (b) for a co-current heat exchanger for a coolant flow rate of 50g/s and CPc=1cal/gK, and in inlet coolant temperature of T20=450K. Vary the coolant rate (1
