1. (20%) The irreversible elementary reaction A(g) - B(g) is conducted in a tubular reactor system consisting of 40 parallel 10 m long tubes with a 5 cm inside diameter. Compound A has a molecular weight of 100 with idea gas behavior. The feeding rate is 314 kg per hour of pure A and the operating pressure of 8.2 atm. It is known that the reaction rate constant for this first-order reaction is 3 hr-' at 300 K and 9 hr at 400 K. What conversion can be achieved if operating temperature set at 500K?
