Which statement correctly describes the ka of a weak acid? the ka is large, and the equilibrium favors products. the ka is large, and the equilibrium favors reactants. the ka is small, and the equilibrium favors products. the ka is small, and the equilibrium favors reactants.

The correct answer is the is small, and the equilibrium favors reactants.

Explanation:

is defined as the dissociation constant of an acid. It is defined as the ratio of concentration of products to the concentration of reactants.

For the dissociation of weak acid, the chemical equation follows:

The expression for dissociation constant, is given as:

There are 3 conditions:

Weak acid is defined as the acid which does not completely dissociates when dissolved in water. Thus, it has dissociation constant very less.

Hence, the correct answer is the is small, and the equilibrium favors reactants.
