Check Your Learning Ethanol and acetic acid react and form water and ethyl acetate,the solvent responsible for the odor of some nail polish removers. 2 15 When 1 mol each of C2H5OH and CH3CO2H are allowed to react in 1 L of the solvent dioxane, equilibrium is established when mol of each of the reactants remains. Calculate the equilibrium constant for the reaction. (Note: Water is not a solvent in this reaction.)
