Consider the equilibrium for the esterification of p-aminobenzoic acid (16) to give ethyl p-aminobenzoate (17) shown in Equation 20.4.
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 17.
c. Which one of the techniques give n in part b is sued in this experiment?
