Chlorobenzene is produced by direct chlorination of benzene. However, a parallel reaction that produces dichlorobenzene hexachloride also occurs. The parallel reactions are shown here. 

The single pass conversion of benzene is 87% and 20% of chlorobenzene produced in the first reaction participates in the second reaction. 100 lbmol/hr benzene and excess chlorine are fed to the reactor. Determine: 

A. the theoretical requirement (lbmol/hr) of chlorine.

B. the yield of chlorobenzene.

C. the selectivity of chlorobenzene relative to dichlorobenzene.

D. the extents of the reactions.
