2837 A A o e k t Because of this functional form 1 st order kinetics are sometimes referred to as exponential decay kinetics. What is the exponential decay formula. N0 is the initial quantity of this substance.
The equation was first proposed by Svante Arrhenius in 1884.
Introduction to Exponential Decay. Incidentally our formula for t gives us an easy way of finding the half-life the time it takes for half the nuclei in a sample to decay. Equation 11 is a constant meaning the half-life of radioactive decay is constant. 1 Answer Humaam H.
