Examples of Chemical Equilibrium
One of the example of a Chemical Equilibrium is shown below:
N2O4 (g) ⇌ 2NO2 (g)
Under suitable conditions N2O4 starts decomposing to 2NO2
N2O4 (g) → 2NO2 (g)
When enough 2NO2 is formed, the backward reaction takes place and 2NO2 reacts to form N2O4
2NO2 (g) → N2O4 (g)
Slowly, the amount of N2O4 decomposing to 2NO2 becomes equal to the amount of 2NO2 reacting to form N2O4, Hence the chemical equilibrium is attained.
N2O4 (g) ⇌ 2NO2 (g)
Here, the double arrow shows the process is in dynamic equilibrium.
There are many more examples of chemical reactions attaining the state of chemical equilibrium, few of them are:
- CaCO3(s) ⇌ CaO(s) + CO2(g)
- 3Fe(s) + 4H2O(g) ⇌ Fe3O4(s) + 4H2 (g)
- H2(g) + I2(g) ⇌ 2HI(g)
- 2H2(g) + O2(g) ⇌ 2H2O(g)
Chemical Equilibrium
Chemical Equilibrium is a condition of a reversible chemical reaction, where the rate of forward and backward reactions are equal. In Chemical equilibrium, the concentrations of the products and reactants remain constant i.e. it does not change with time. This is a state after which there are no observable changes in the properties and the system becomes constant. In this state, the forward reaction proceeds at the same rate as the reverse reaction.
In this article, we will learn more about chemical equilibrium, its types, its examples, and more, so Let’s get started.
