1) The esterification of acetic acid with ethanol to form ethyl acetate has an equilibrium constant of 3.4 at 25 degree C.
If you dissolve 0.231 mol of acetic acid (CH3CO2H) in 1.00 L of ethanol (C2H5OH), what would be the concentration of the ethyl acetate (C4H8O2) formed at equilibrium? Note: ethanol is the solvent in this reaction.
For the gas-phase reaction shown below, choose the answer which indicates how the rate of change of H2O is related to the rate of change of C3H6.
