In the gas phase, acetic acid exists in an equilibrium of monomer and dimer molecules. (The dimer consists of two molecules linked through hydrogen bonds.)
The equilibrium constant, Kc, at 25 degrees C for the monomer-dimer equilibrium
2 CH3CO2H ⇌ 9CH3CO2H)2
has been determined to be 3.2 x 10^4. Assume that acetic acid is present initially at a concentration of 3.8x10^-4 mol/L at 25 degrees C and that no dimer is present initially.
a) What percentage of the acetic acid is converted to dimer?
