Consider an example of reaction in series, benzene is chlorinatedin a semi batch process where chlorine is bubbled through awell-agitated solution of benzene at 55 degrees C. Assume thatchlorine is added sufficiently slowing that (i) Cl2 and HClconcentrations in the liquid phase are small (ii) all the Cl2reacts and (iii) the liquid has a constant density. Under thesereaction conditions, the significant reactions are the threesubstitution ones leading to mono-, di-, and tri-chlorobenzene
C6H6 + Cl2 --> C6H5Cl + HCl
C6H5Cl + Cl2 --> C6H4Cl2 + HCl
C6H4Cl2 + Cl2 --> C6H3Cl3 + HCl
The selectivity of benzene to mono-chlorobenzene is 0.25 and theconversion of benzene is 50%. If the process produces 30 moles oftri-chlorobenzene per 100 moles of benzene feed, how many moles ofchlorine are required?
