Question

What is the Half-Life Period?

Answer 1

Half-life period

• “The half-life of a reaction or radioactive substances is the time in which the concentration of a reactant is reduced to one-half of its initial concentration”.
• It is represented as$t_{1/2}$.

Uses of half-life period

• Half-life is used to calculate the age of a substance.
• It is also used in chemical kinetics.
• For a first-order reaction, the half-life is independent of the initial concentration.
