Question

In organic substitution the reactions, the product generatedby the reaction is prone to additional substitution. A semi-batch reactor was used to produce mono-chlorobenzene by reacting benzene with chlorine. The reactor was charged with 18 mole of liquid benzene. A stream of gaseous chlorine bubbled through the liquid, and the chlorine not reacted upon was recycled. During the operation, monochlorobenzene reacted with the chlorine to produce dichlorobenzene, and the dichlorobenzene reacted with the chlorine to produce tri-chlorobenzene.

C6H6(l) + Cl2(g) -------> C6H5Cl(l) + HCl(g)

C6H5Cl(l) + Cl2(g) -------> C6H4Cl2(l) +HCl(g)

C6H4Cl2(l) + Cl2(g) ------> C6H3Cl3(l) +HCl(g)

At the end of the operation, the reactor contained 12 mole of benzene and a product mixture inwhich the amount of mono-chlorobenzene was three times the amount of dichlorobenzene, and the amount of the latter was twice the amount of tri-chlorobenzene. The total amount of chlorine fed during the operation was 41 mol Cl2. Find:

a) the fractional conversion of benzene

b) the amounbt of each liquid component besides benzene in the reactor: mol C6H5Cl, mol C6H4Cl2, C6H3Cl3

c) the amount of HCl produced

d)the fractional concersion of chlorine
