For the given proton transfer reaction, which side of the reaction is favored, and by what numerical factor, is to be predicted. Concept introduction: A proton transfer reaction is the one in which a Bronsted Lowry base reacts with a Bronsted Lowry acid to form a conjugate base and a conjugate acid respectively. A reaction’s tendency to form products is described by its equilibrium constant Keq. A very large Keq favors the products side, while a very small Keq value heavily favors the reactants. A proton transfer reaction favors the side opposite the stronger acid (i.e., opposite to the lower pKa value). Each difference of one in pKa values between the two acids corresponds to a power of ten by which that side of the reaction is favored.
