Ethanol in water is in equilibrium with ethoxide and hydronium ion. K for this reaction is 1.19 × 10-16 at room temperature. Is ethanol or ethoxide favoured? What is the pk? of ethanol ? OH + H?O + H?0 Ethanol. pka = 15.9 Ethanol. pka = -1.9 Ethoxide. pka = 15.9 Ethoxide. pka = -1.9 In acid-base reactions, the weaker (more stable, less acidic, less reactive) acid-base pair will be thermodynamically favoured. For the following reaction, which side is the weaker acid-base pair? Should reactants or products be favoured? NH? H?O NH3 OH pK?= 15.7 PK? = 33 Products. Reactants O Reactants. Reactants Reactants.
