The equilibrium of Fischer esterification reactions in general is slightly towards product formation. The equilibrium can be made more favorable for product formation by all of the following except: a. Increasing the concentration of the 2-phenylacetic acid b. Increasing the concentration of the ethanol c. Removing water from the reaction mixture d. Increasing the concentration of H2SO4 e. Removing ethyl -2-phenylacetate as it is formed
