A fresh feed stream contains 50.0mol/s each of A and B and no other compounds. It is mixed with a recycle stream and enters a reactor. The reaction A + B ? C is carried out in the reactor. The reaction reaches equilibrium and 50% of the entering A is converted into C. The reactor effluent is sent to a distillation column.

The entire process operates at steady state. A. The recycle stream is 49.5 mol% A and 49.5 mol% B. B. The equilibrium constant in the reaction is 1. C. The molar flow rate of the product stream is 50.0 mol/s. D. All of the above have to be true. E. None of the above has to be true, though they could be true.
