The time required for a 40 g sample of potassium- 40 in a rock sample to reduce to 10 g is to be predicted. Concept introduction: The time required for the concentration of the reactant to reduce to half of its initial concentration gives the half-life of the reaction. The half-life of the reaction depends on the initial concentration of the reactant except for the first order reaction.
