Keywords Differential equations Bouguer–Lambert– Beer law Time constants Chemical kinetics Radioactive decay Nuclear magnetic resonance RC constant Introduction ‘‘Differential equations are extremely important in the history of mathematics and science, because the laws of nature are generally expressed in terms of differential equations.

Nov 25, 2014 · In general, all chemical reactions can be described mathematically by first-order differential equations. Their solutions, however, depend directly on the nature of the chemical reaction itself. The latter is characterized by the so-called reaction order, which has nothing what so ever to do with the order of a differential equation. The ...
