Explain dynamic nature of chemical eqilibrium with suitable example
Answers
Answer:
In chemistry, and in physics, a dynamic equilibrium exists once a reversible reaction occurs. Substances transition between the reactants and products at equal rates, meaning there is no net change. Reactants and products are formed at such a rate that the concentration of neither changes. It is a particular example of a system in a steady state. In thermodynamics, a closed system is in thermodynamic equilibrium when reactions occur at such rates that the composition of the mixture does not change with time. Reactions do in fact occur, sometimes vigorously, but to such an extent that changes in composition cannot be observed. Equilibrium constants can be expressed in terms of the rate constants for elementary reactions.
Answer:
At chemical equilibrium state, the rates of the forward and the backward reactions are equal and the concentrations of the reactants and the products reach constant values. At chemical equilibrium the reaction still continues to take place in both the directions with the same rates. The reactants continue to form the products while the products also continue to form the.reactants. Because of such a situation at the equilibrium state in the reaction system, the chemical equilibrium is called a dynamic equilibrium
