Half-Life in Chemistry: Calculations and Examples - PSIBERG The half-life of a substance (atoms, molecules, or ions) refers to the time it takes for half of its given amount to radioactively decay. The rate at which reactants are converted into products is always proportional to the concentration of reactants present. This study of the rate of decomposition of chemical species is called rate kinetics.
