As we click on New; button , a form is displayed as shown in Figure 2.29. In this
f
form, we need to enter the stoichiometric coeficient as well as exponent for all
components. The exponents represent the order of the reaction with respect to each
component. Note that there are two types of reactions [kinetic (rate-controlled reactions)

and equilibrium] permitted under Power law reaction ID .
