Chemical Kinetics and Laplace Transform

Chemical kinetics is the quantitative study of chemical systems that are
changing with time. (Thermodynamics, another of the major branches of
physical chemistry, applies to systems at equilibrium—those that do not
change with time.)[1]

Laplace Transforms can be used to handle moderately complicated chemical systems. But these techniques work only for linear (1st-order) systems. This can be used in handling mixed order reaction equations, such as “mixed second order” reactions.
