Abstract
Esters are important industrial compounds. Different esters have different demands in the current industry. The reaction rate of the reaction plays an important role in the production of the ester which could affect the production of the ester. Esterification is a reversible reaction and thus this affects the amount of ester produced as ester hydrolysis changes it back to its reactants. Very little data is available on how does the carbon chain length of carboxylic acid and alcohol affects the rate constant and equilibrium constant of esterification. Thus, the research topic of this investigation is: How does the carbon chain length of the alcohols and carboxylic acids affect the rate constants of the forward and backward reactions and equilibrium constant of the esterification reaction?
The affect of the carbon chain length of carboxylic acid and alcohol was measured separately by first reacting carboxylic acids with ethanol and then alcohols with ethanoic acid.
Each reaction was repeated four times and the amount of reactant and catalyst was varied. The initial rate was measured by plotting the graph of concentration of the carboxylic acid with respect to time.
Thus, the order of reaction with respect to each reactant was measured. The reaction equation was then formed and the rate
