... CH3CO2H(aq) + H2O() Æ CH3CO2–(aq) + H3O+(aq) K = 1.8 10–5 at 25 ºC The small value of K means that at equilibrium the concentration of reactants is much larger than the concentration of products. This is a reactant-favored reaction, and at equilibrium there will very little CH3CO2– or H3O+ in the ...
