Answer

Brief Explanations:

The acid - dissociation constant ($K_a$) measures the extent of acid dissociation. For a weak acid, the dissociation is incomplete. A small $K_a$ value indicates that the concentration of products (dissociated ions) is low compared to the concentration of the undissociated acid (reactant) at equilibrium. So, the equilibrium favors the reactants.

Answer:

The $K_a$ is small, and the equilibrium favors reactants.
