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, K., at 25 °C for the monomer-dimer equilibrium 2 CHgCOzH+(CH3CO,H)2 has been determined to be 3.2 × 10¹. Assume that acetic acid is present initially at a concentration of 4.0 x 10 mol/L at 25 °C and that no dimer is present initially. a what percentage of the acetic acid is converted to dimer? Percentage = % b As the temperature increases, in which direction does the equilibrium shift? (Recall that hydrogen-bond formation is an exothermic process.) Increasing the temperature will shift the equilibrium to the right. Increasing the temperature will shift the equilibrium to the left. O No shift will occur.
