Species C
Species D
We will specify V, CAo, Cbo along with the specific reaction rates kij. This formulation leaves us with four equations and four unknowns (CA, CB, CC, and CD).
Use Polymath's nonlinear equation solver. Put the combined mole balance and rate laws in the following form

CASE 3: Semibatch
