= A 200-dm3 constant-volume batch reactor is pressurized to 20 atm with a mixture of 75% A and 25% inert. The gas-phase reaction is carried out isothermally at 227C. (a) Assuming that the ideal gas law is valid, how many A B+C moles of A are in the reactor initially? What is the initial concentration of A? (b) If the reaction is first order: -ra = kCA with k = 0.1-1. Calculate the time necessary to consume 99% of A. (c) Repeat (b) assuming the reactor contents initially are 100% A. dm (d) If the reaction is second order: -"A = kC with k = 0.7 mol. min Repeat (c) to calculate the time to consume 80% of A. Also, calculate the pressure in the reactor at this time if the temperature is 227C. min
