In the preparation of isoamyl acetate, a student reported a % yield of 66.6%.Assuming that he used equimolar amounts of the starting materials,what is the equilibirium constant of the esterification process? I need conc of products & conc of reactants to get Keq but how do i get that? They only said that equimolar amounts were used & that means there is no limiting or excess reagent. All ive managed to get so far is that i need to use the reaction: CH3CO2H + HOCH2CH2CH(CH3)2 ---> CH3CO2CH2CH2CH(CH3)2 +H2O Keq= [CH3CO2CH2CH2CH(CH3)2] / [CH3CO2H] [HOCH2CH2CH(CH3)2] But how do i get these conc.?
