The reversible gas-phase chemical reaction A reversible 2B takes place in a steady state tubular reactor operated at a constant pressure of 2 atm and temperature of 120 degree C. The forward reaction is first-order, and the backward reaction is second order. We want to process a 100 mole/min stream of pure A. At the operating conditions (120 degree C), equilibrium constant is 0.31 L/mol. What is the equilibrium composition at 120 degree C?
