A liquid-phase mixture of 450 mL of acetic acid, 300 mL of ethanol, 2.00 mL of water, and 2.00 mL ethyl acetate are mixed together at 298 K, where the following reaction will occur: CH3COOCH2CH3 +H2O CH3COOH +CH3CH2OH, Kc = 3440 Will the reaction occur from left-to-right or right-to-left (as written)? Please support your answer. (Hints: Can you calculate concentrations of the chemical species initially in appropriate units. Starting with the densities, i.e., specific gravities, and volumes, molar amounts of each species can be determine. Also, the total volume can be calculated; assume the volume change due to mixing the four solvents is zero. Can you calculate Qc?)

One type of breathalyzer employs a fuel cell to measure the quantity of alcohol in the breath. When a suspect blows into the breathalyzer, ethyl alcohol is oxidized to acetic acid at the anode: CH3CH2OH(g)+4OH−(aq)→HC2H3O2(g)+3H2O(l)+4e− At the cathode, oxygen is reduced: O2(g)+2H2O(l)+4e−→4OH−(aq) The overall reaction is the oxidation of ethyl alcohol to acetic acid and water. When a suspected drunk driver blows 185 mL of his breath through this breathalyzer, the breathalyzer produces an average of 325 mA of current...

The purpose of the lab was to find the equilibrium constant of
the rxn of acetic acid and ethanol to yield ethyl acetate and
water. Hydrochloric acid is used as a catalyst. We have to
determine the equilibrium concentrations of all the species (water
included) present at equilibrium. In test tubes, different
concentrations of the equilibrium system were prepared then
titrated with NaOH to determine the total acid content of the
system at equilibrium. From this you will be able...
