Step by Step Solution

Equilibrium

The state of equilibrium arises when no more reactants and products are changing concentrations, i.e., the rate of forward reaction becomes equal to the rate of backward reaction.

Direction of equilibrium

The direction of equilibrium favors the side of lower energy. Generally, weak acids and weak bases have lower energy. So, the equilibrium favors the side of weaker acids and bases, i.e., an acid with a higher value.

Products and direction of equilibrium of the given compounds

a. The value of products is higher, which means that the acid on the product's side is weaker and hence possesses lower energy. So, the equilibrium favours the products side.

The reaction of a

b. The value of reactants is higher, which means that the acid on the reactant's side is weaker and possesses lower energy. So, the equilibrium favors the reactant's side.

The reaction of b.

c. The value of reactants is higher, which means that the acid on the reactant's side is weaker and possesses lower energy. So, the equilibrium favors the reactant's side.

The reaction of c.

d. The value of products is higher, which means that the acid on the product's side is weaker and hence possesses lower energy. So, the equilibrium favors the products side.

The reaction of d.
