Which of the following is accurate, based on this process description?
A fresh feed stream contains 50.0 mol/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 at P= 0.1 MPa. The reaction reaches equilibrium and the reactor effluent is 40 mol% A, 40 mol% B and 20 mol% C. The reactor effluent is sent to a flash vessel, and the streams leaving the flash vessel are at VLE. The liquid leaving the flash is essentially pure C and is the product from the process. The vapor leaving the flash contains 49.0 mol% A, 49.0 mol% B and 2.0 mol% C, and this entire stream is recycled. The entire process operates at steady state.
