A+B0 Is first order with respect to A and zero order with respect to B. It has a rate constant k -0.0040 min' at 300 K and an E/R = 7500 K. Pure A and pure B both have concentrations of 1.2 mol/L. a) Pure A is fed to a 700 liter PFR at a flow rate of 30 L/min while pure B is fed in 5% excess. If the reaction occurs isothermally at 75 C what is the expected conversion? See Figure below: (76%) Pure A V = 30 liters/min PER Volume = 700 liters Pure B If instead a 700 liter batch reactor is filled with a mixture of A and B (with 5% excess B) predict the time required to achieve the same conversion as determined in part A. Note: if you could not determine the conversion in part a please assume a conversion of 85%. (11.4 minutes) CHE 32014
