Name: Chan Lo Ho Class: 6A Class no.: 4 Date: EQ3 Determination of the Equilibrium Constant for Esterification - Ethanoic Acid and Propan-1-ol Objectives To determinate the Equilibrium Constant for Esterification of ethanoic acid and propan-1-ol Theory Esterification is a reaction that combines an alcohol with an organic acid, with a water molecule is being taken out, and ester is formed. A concentrated acid catalyst speeds up the esterifications. This time H2SO4 is used. Esterificaiton is a slow and reversible reaction. The equation for the reaction between an acid RCOOH and an alcohol R'OH (where R and R' can be the same or different) is: At equilibrium, the concentrations of both reactants and products are constant. The number values for "K" are got from experiments by measuring the equilibrium concentrations. And the number value tells the equilibrium ratio of products to reactants. The value of K is large when the products dominate the mixture and vice versa. The expression for...
