The correct answer is The equilibrium constant for this reaction changes as the pH changes.
Explanation:
The equilibrium constant of a reaction depends of pH and viceverca.There is a equation that link pH with equilibrium constant Ka(for assumption).The equation is given below,
pH=pKa+log[A-/HA]
where[A-] is the concentration of conjugate base and [HA] is the concentration of conjugate acid.
