Does Equilibrium Favor the Weaker Acid?

The stronger the acid the lower the pKa value. Equilibrium favors the side of the weaker acid.

Which side of the equilibrium is favored?

Weak acids and bases are lower in energy than strong acids and bases, and because equilibria favor the reaction side with the lowest-energy species, acid-base reactions will go to the side with the weakest acids and bases. As a rule, the equilibrium of a reaction will favor the side with weaker acids and bases.

Do strong acids go through equilibrium?

Strong acids are completely dissociated in water. Their conjugate bases are weak. ... In any acid-base reaction, the equilibrium will favor the reaction that moves the proton to the stronger base.
