yet deterministic manner, a behavior noted in the three coupled
Lorenz equations.
autocatalytic reaction (in chemical dynamics): Those reactions in which at
least one of the products (on the right-hand side of the chemical equa-
tion) is a reactant (on the left-hand side of the chemical equation).
An example of a simple autocatalytic reaction is
