Proton Transfer in Acid-Base Reaction

Acids and bases are fundamental concepts in chemistry, particularly in understanding reactions in biological systems. A common way to define acids and bases is through the Bronsted-Lowry theory, where an acid is a proton (H⁺) donor and a base is a proton acceptor. Consider the following reaction:

HA + B ⇌ A^- + HB⁺

In this reaction, HA represents a weak acid and B represents a weak base. Which of the following statements about this reaction is true?
