According to the first-order kinetics, the decay constant is given by: Where, a = initial amount of the substance = 100 a-x = remaining amount of the substance after t time = 28.0 t = time = 6.16 hLet's put these values into the formula:Radioactive decay follows first-order kinetics. The decay constant (λ) and half-life of a substance are related as follows:Hal-life of copper-64 is = 3.35 h
