Consider the equilibrium for the esterification of p-aminobenzoic acid to give ethyl p-aminobenzoate
conc. H2SO4
p-aminobenzoic acid + CH3CH2OH ---------> benzocaine +H2O
(catalyst)
a. Write the mathematical expression for the equilibrium constant, Keq, as a function of the concentrations of the products and reactants for this reaction
b. Provide two specific ways whereby the Le Chatelier principle may be applied to this equilibrium to drive the reaction completely to the ester Ethyl p-aminobenzoate (benzocaine)
c. Which one of the techniques given in Part b is used in this experiment.
