Benzylamide is the product obtained from the liquid-phase reaction of ammonia and benzoyl chloride:

(a) Taking benzoyl chloride as your basis of calculation, set up a stoichiometric table for a batch system.
(b) If the initial mixture consisted solely of ammonia at a concentration of 6 gmol/L and benzoyl chloride at a concentration of 2 g mol/L, calculate the concentrations of ammonia and benzylamide when the conversion is 25%.
(c) Taking ammonia as your basis of calculation, explain how your stoichiometric table would be different for a flow system.
