Question

What is chemical and physical equilibrium?

Answer 1

Chemical equilibrium

• In the case of chemical equilibrium, the rates of the forward and reverse reactions become equal.
• In this case, there is no net change in the concentrations of the reactants and the products.
• An example of chemical equilibrium is as follows:-

${\mathrm{H}}_2\left(\mathrm{g}\right)+{\mathrm{I}}_2\left(\mathrm{g}\right)\rightleftharpoons 2\mathrm{HI}\left(\mathrm{g}\right)$

Physical equilibrium

• An equilibrium between two different physical states of the same substance is referred to as physical equilibrium.
• Physical equilibriums show no change in the physical states of matter that are involved in the equilibrium.
• An example of physical equilibrium is as follows:-

${\mathrm{H}}_2\mathrm{O}\left(\mathrm{s}\right)\to {\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)$
