Question

1. What is meant by chemical equilibrium?

2. Is it different from a "dynamic equilibrium"? If so, explain how

Answer 1

1) Chemical equilibrium is a special case of reversible reaction. When the rate of forward reaction (i.e.- reactant to product) becomes equal to rate of backward reaction (i.e.- product to reactant), it is called as the state of chemical equilibrium. The chemical equilibrium is expressed interms of equilibrium constant, which is the ratio between, molar concentration of product to molar concentration of reactant each raised to the power number of times they exist in the balanced chemical equation.

2) Chemical equilibrium is same as dynamic equilibrium.

At equilibrium the rate of forward reaction becomes equal to rate of backward reaction , such that, no further change in concentration of reactant and product takes place. However, a rapid interconversion of reactant to product and again back to reactant takes place. Thus, chemical equilibrium is a dynamic phenomenon and hence it is otherwise called as dynamic equilibrium.
