This is a Reaction/Chemical Reactor Engineering question. Please provide full, clear working for the answer with legible handwriting and explanation, if needed.

Pleass know I am depending on Chegg to learn and pass this course. Thank you so much.

Calculate the required length of a plug flow reactor to produce B at a total rate of 150,000 tonnes/year following elementary gas phase reaction AB+C. The total conversion when the system operates isothermally at 1500K and constant pressure 5atm is 90%. The rate constant value at 1000K is 0.075s1 and the internal diameter of the PFR tube is 30 cm. The molecular weight of B is 28g/mol while the activation energy is 100kcal/mol. Select one: a. 207m b. 158m c. 220m d. 197m e. 143m f. 105m Calculate the required length of a plug flow reactor to produce B at a total rate of 150,000 tonnes/year following elementary gas phase reaction AB+C.
