Ethyl acetate is synthesized in a nonreacting solvent (not water) according to the following reaction: CH 3 CO 2 H Acetic acid + C 2 H 5 OH Ethanol ⇌ CH 3 CO 2 C 2 H 5 Ethyl acetate + H 2 O K = 2.2 For the following mixtures (a-d), will the concentration of H 2 O increase, decrease, or remain the same as equilibrium is established? a . [CH 3 CO 2 C 2 H 5 ] = 0.22 M , [H 2 O] = 0.10 M , [CH 3 CO 2 H] = 0.010 M, [C 2 H 5 OH] = 0.010 M b . [CH 3 CO 2 C 2 H 5 ] = 0.22 M, [H 2 O] = 0.0020 M, [CH 3 CO 2 H] = 0.0020 M, [C 2 H 5 OH] = 0.10 M c . [CH 3 CO 2 C 2 H 5 ] = 0.88 M, [H 2 O] = 0.12 M, [CH 3 CO 2 H) = 0.044 M, [C 2 H 5 OH] = 6.0 M d . [CH 3 CO 2 C 2 H 5 ] = 4.4 M, [H 2 O] = 4.4 M, [CH 3 CO 2 H] = 0.88 M, [C 2 H 5 OH] = 10.0 M e. What must the concentration of water be for a mixture with [CH 3 CO 2 C 2 H 5 ] = 2.0 M , [CH 3 CO 2 H] = 0.l0 M , and [C 2 H 5 OH] = 5.0 M to be at equilibrium? f . Why is water included in the equilibrium expression for this reaction?
