Question
An ester is formed in the reaction of an organic acid with analcohol. For example, in the reaction of acetic acid (CH3COOH) withethanol (C2H5OH) in an organic solvent, the ester known as ethylacetate (CH3COOC2H5) and water form. The reaction is CH3COOH + C2H5OH(g) <----> CH3COOC2H5 +H2O Kc = 4 at 500K If the initial concentrations of CH3COOH and C2H5OH are0.03mol/L and 0.047mol/L, respectively, and the concentration ofwater in the initial mixture is 0.018mol/L, calculate theequilibrium concentration of ester. Answer in units of mol/L. An ester is formed in the reaction of an organic acid with analcohol.
