In the gas phase, acetic acid exists as an equilibrium of monomer and dimer molecules. (The dimer consists of two molecules linked through hydrogen bonds.) The equilibrium constant, , at 25 °C for the monomer-dimer equilibrium has been determined to be . Assume that acetic acid is present initially at a concentration of mol/L at 25 °C and that no dimer is present initially. a What percentage of the acetic acid is converted to dimer? Percentage = %
