If the partial orders of reaction are integers, we can solve the integral by way of the integrand
decomposition (rational function) into the sum of fractions, see basic course of mathematics.
The same procedure can be used when there are more reactants.


9.2.7 Summary of relations.


Let us consider the chemical reaction


aA +bB +cC→products. (9.81)

The following table sums up the integrated forms of the kinetic equations presented in this
section. The column “Eq.” gives the number for the integrated form of the kinetic equation.
The partial orders of reaction with respect to components A, B, C are denoted by symbolsα,
β,γ. If the relation applies for arbitrary values of stoichiometric coefficients, these coefficients
are denoted using the symbolsa,b,c. The initial composition of the reacting mixturecA0,cB0,
cC0is either stoichiometric (S) or arbitrary (A).
