Question

Write five important aspects of chemical equilibrium.

Answer 1

Hint: Equilibrium is the state of a process in which the rate of forward reaction is equal to rate of backward reaction. During equilibrium the properties like temperature, pressure and even the concentration of the system does not show any change with respect to time.

Complete step by step answer:
If in equilibrium the opposing processes involves chemical changes, then the equilibrium is known as chemical equilibrium or it is also defined as the state of chemical reactions when the rate of the forward reaction is equal to the rate of the backward reaction and also the concentration of reactants and products are constant. An example is mentioned below:
\[C{{H}_{3}}C{{O}_{2}}H+{{H}_{2}}O\rightleftharpoons C{{H}_{3}}C{{O}^{-2}}+{{H}_{3}}{{O}^{+}}\]

Five important aspects of chemical equilibrium are mentioned below:
At equilibrium the rate of the forward reaction is equal to the rate of the backward reaction.
All the reactants and products from the reaction are present in equilibrium.
The concentration of the reactants and the products reaches a constant value and then they are known as equilibrium concentration.
If a catalyst is used in the reaction it does not affect the position of equilibrium.
If we change the temperature, pressure, volume and concentration changes the position of the equilibrium.

Note: Chemical equilibrium is dynamic in nature, it can be obtained from both sides. The chemical equilibrium in which ions in aqueous solution are involved is known as ionic equilibrium.
The equilibrium in which the opposing processes involves only physical changes is known as physical equilibrium. The equilibrium establishes between vapor and water is an example of physical equilibrium.
