The kinetics of a reaction is the rate of transformation of a chemical (or biological) element into (a) product(s).
Its unit is expressed in mol.s-1.
The kinetics of a reaction is often estimated using Arrhenius' Empirical Law.
The kinetics of a reaction takes place until chemical equilibrium is reached.
If 10 moles of A is reacted with 100 moles of B to produce C. If the reaction kinetics of A is 0.5 mol.s-1. Then the chemical reaction will have a duration of 20s.
