Solution: Ethyl acetate is synthesized in a nonreacting solvent (not water) according to the following reaction:CH3CO2H + C2H5OH ⇌ CH3CO2C2H5 + H2O                K = 2.2 Acetic acid    Ethanol      Ethyl acetatee. What must the concentration of water be for a mixture with [CH 3CO2C2H5] = 2.0 M, [CH3CO2H] = 0.10 M, and [C2H5OH] = 5.0 M to be at equilibrium?

Solution: Ethyl acetate is synthesized in a nonreacting solvent (not water) according to the following reaction:CH3CO2H + C2H5OH ⇌ CH3CO2C2H5 + H2O                K = 2.2Acetic acid    Ethanol      Ethyl acetat

Problem

Ethyl acetate is synthesized in a nonreacting solvent (not water) according to the following reaction:

CH3CO2H + C2H5OH ⇌ CH3CO2C2H5 + H2O                K = 2.2
Acetic acid    Ethanol      Ethyl acetate

e. What must the concentration of water be for a mixture with [CH 3CO2C2H5] = 2.0 M, [CH3CO2H] = 0.10 M, and [C2H5OH] = 5.0 M to be at equilibrium?
