The Half-Life of a chemical reaction can be defined as the time taken for the concentration of a given reactant to reach 50% of its initial concentration.
half-life n 1.(General Physics) the time taken for half of the atoms in a radioactive material to undergo decay. Symbol:τ 2.(Biology) the time required for half of a quantity of radioactive material absorbed by a living tissue or organism to be naturally eliminated (biological half-life...

For a given reaction the half-life, t1/2, of a reactant is the time required for its concentration to reach a value that is the arithmetic mean of its initial and final (equilibrium) value.
Chapter 11: Nuclear Chemistry Search for: 11.2 Half-LifeLearning Objectives Define half-life. Determine the amount of radioactive substance remaining after a given number of half-lives. Whether or not a given isotope is radioactive is a characteristic of that particular isotope. Some isotopes are...
