Derivation of radioactive decay equation

Calculations Using the First Order Rate Equation: r = k[N] Since the rate of radioactive decay is first order we can say: r = k[N] 1, where r is a measurement of the rate of decay, k is the first order rate constant for the isotope, and N is the amount of radioisotope at the moment when the rate is measured.

Answer 2

Explanation:

Lambda(λ) the Decay Constant and exponential decay The rate of decay(activity, A) is proportional to the number of parent nuclei(N) present. λ( ...
