Answer:
The equilibrium will shift to the reactants and increase the concentration of CH3COOH
Explanation:
According to Le Chatelier's principle when a system at equilibrium is subjected to a change in temperature, pressure, concentration etc then the equilibrium will shift in a direction to undo the effect of the induced change.
The given reaction is:
CH3COOH ↔ CH3COO-(aq) + H+(aq)
CH3COONa exists as ions i.e. CH3COO- and Na+. Therefore, addition of CH3COONa will introduce more CH3COO- ions into the system as a result the equilibrium will shift to the left i.e. towards the reactants and will produce more of CH3COOH
