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?

P6-66 (Membrane reactor) The first-order, gas-phase, reversible reaction AB+2C is taking place in a membrane reactor. Pure A enters the reactor, and B diffuses out through the membrane. Unfortunately, a small amount of the reactant A also diffuses through the membrane. (a) Plot and analyze the flow rates of A, B, and C and the conversion X down the reactor, as well as the flow rates of A and B through the membrane. (b) Next, compare the conversion profiles in...

PROBLEM 2 The elementary liquid phase irreversible reaction (A+B -> C) takes place in a 1 m² Mixed Flow Reactor with the equimolar mixture of A and B at the volumetric feed flow rate of 0.5 m3/min, the feed concentration of A equal to 1 mol/L, and the feed temperature of 300K. When the reaction takes place under isothermal conditions at 300K the conversion of A is 30%. When the reaction takes place adiabatically the exit temperature is 350K and...
