(B) When dilute $HCl$ is added to the solution,it dissociates to provide $H^{+}$ ions: $HCl \rightarrow H^{+} + Cl^{-}$.This increases the concentration of $H^{+}$ ions in the system.According to Le Chatelier's principle,the equilibrium will shift in the backward direction to consume the excess $H^{+}$ ions.As a result,the concentration of $CH_3COO^{-}$ will decrease.The equilibrium constant $(K_a)$ remains unchanged because it depends only on temperature.

The following equilibrium exists in aqueous solution: $CH_3COOH \rightleftharpoons CH_3COO^{-} + H^{+}$. If dilute $HCl$ is added,without change in temperature,the:
