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
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
- increase
- decrease
- remain the same
b. [ch3co2c2h5]=0.22 m [h2o]=0.20 m, [ch3co2h]=0.020 m, [c2h5oh]=0.010 m
- increase
- decrease
- remain the same
c. [ch3co2c2h5]=0.88 m [h2o]=0.12 m, [ch3co2h]=0.044 m, [c2h5oh]=6.0 m
- increase
- decrease
- remain the same
d. [ch3co2c2h5]=4.4 m [h2o]=4.4 m, [ch3co2h]=0.088 m, [c2h5oh]=10.0 m- increase- decrease- remain the same
e. what must the concentration of water be for a mixture with [ch3co2c2h5]=3.0 m, [ch3co2h]=0.10 m, [c2h5oh]=6.0 m and to be at equilibrium?
