kinetics

The irreversible elementary reaction 2A B takes place in the gas phase of an isothermal 50 L tubular (CSTR) reactor at 760 Torr. Product B is the only condensable component in the system. The vapor pressure of B at 600K is 150 Torr. What is the conversion of A when condensation occurs? What is the initial flow of A and flow rate of B leaving the reactor at XA = 25%? What is the initial flow of A at XA= 80%? Additional Data: To = 300 K, T = 600 K, k = 100 L/mol-sec, k., = 2/sec
