ChemistryPrinciples of Instrumental AnalysisThe counting rate of sample 64 C u is 4225cpm. The counting rate of sample after 10.00hr is 2898cpm. The half time of the sample 64 C u is to be determined. Concept introduction: According to first order of kinetics: ln ( N N 0 ) = − λ t Here, N and N o are final and initial concentrations, λ is decay constant and t is time. t 1 / 2 ( h a l f − t i m e ) = ln 2 λ Or, t 1 / 2 = 0.693 λ Here, t 1 / 2 is half-life time.Start your trial now!
