The reaction A₁₃B↔C+2D is carried out in the gas phase, in a steady-state re actor at T = 500 K and P = 1 bar. At these conditions, the equilibrium constant is K₅₀₀ = 0.2500. The reacting mixture behaves like an ideal gas and the stream exiting the reactor is at equilibrium. 

A. If the reactor feed contains 1000 mol/hr each of A and B, what are the contents of the exiting stream? 

B. If the reactor feed contains 1000 mol/hr of A, 3000 mol/hr of B, and 2000 mol/hr of the inert I, what are the contents of the exiting stream? 

C. If the reactor feed contains 1000 mol/hr of A, 1000 mol/hr of B, and 500 mol/hr of C, what are the contents of the exiting stream?
