Question

C) in a semibatch reactor. The feed stream 3. (10 pts.) Consider an elementary liquid-phase reaction (A+B containing B with a constant concentration (CBo) and a constant flow rate (Do) is slowly fed to a reactor containing pure A with an initial concentration (CAo). Derive three differential equations for the mole balances of A, B, and C. Please provide the steps in detail, because the credits will be given based on the detailed procedure. 1
