$CH_3COOH + H_2O \rightleftharpoons H_3O^{+} + CH_3COO^{-}$ પ્રક્રિયા માટે સંતુલન અચળાંક $K$ લખો.

• A
  $K = \frac{[H_3O^{+}][H_2O]}{[CH_3COO^{-}][CH_3COOH]}$
• B
  $K = \frac{[H_3O^{+}][CH_3COO^{-}]}{[CH_3COOH][H_2O]}$
• C
  $K = \frac{[H_3O^{+}][H_2O]}{[CH_3COOH][CH_3COO^{-}]}$
• D
  $K = \frac{[H_2O][CH_3COO^{-}]}{[H_3O^{+}][CH_3COOH]}$
