Which of the following has to be true based on this process description?
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 bottom product from the column is 98.0 mol% pure C and is the product from the process. The top product contains 1.0 mol% C and the entire top product is recycled. The entire process operates at steady state.
