Question:

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

For the following mixtures (a–d), will the concentration of H2O increase, decrease, or remain the same as equilibrium is established?

a. [CH3CO2C2H5] = 0.22 M, [H2O] = 0.10 M, [CH3CO2H] = 0.010 M, [C2H5OH] = 0.010 M

b. [CH3CO2C2H5] = 0.22 M, [H2O] = 0.0020 M, [CH3CO2H] = 0.0020 M, [C2H5OH] = 0.10 M

c. [CH3CO2C2H5] = 0.88 M, [H2O] = 0.12 M, [CH3CO2H] = 0.044 M, [C2H5OH] = 6.0 M  

d. [CH3CO2C2H5] = 4.4 M, [H2O] = 4.4 M, [CH3CO2H] = 0.88 M, [C2H5OH] = 10.0 M

e. What must the concentration of water be for a mixture with [CH3CO2C2H5] = 2.0 M, [CH3CO2H] = 0.10 M, and [C2H5OH] = 5.0 M to be at equilibrium?

f. Why is water included in the equilibrium expression for this reaction?
