Question

What are the characteristics of dynamic equilibrium?

Answer 1

1. Dynamic equilibrium: The chemical equilibrium is also dynamic just like physical equilibrium. The reaction will be still going in the forward as well as reverse direction. But the rate of forward reaction becomes equal to the rate of reverse reaction. An example for the dynamic equilibrium is:

$$\begin{gathered} {\mathrm{H}}_2\left(\mathrm{g}\right)+{\mathrm{I}}_2\left(\mathrm{g}\right)\rightleftharpoons 2\mathrm{HI}\left(\mathrm{g}\right) \\ \mathrm{Hydrogen}\mathrm{Iodine}\mathrm{Hydrogen}\mathrm{iodide} \end{gathered}$$

Characteristics of dynamic equilibrium-

1. The observable properties, such as concentration, density, color, pressure, etc., remain constant at constant temperature:
2. Equilibrium can be attained from either direction.
3. Usage of a catalyst does not alter the position of equilibrium.
4. Equilibrium state proceeds indefinitely unless it is disturbed by external factors.
