The previous paper was concerned with determining the number of terms in the equation modelling a polyreactive reactant on the basis of so-called equalization in the dependence of the minimum sums of deviations squared on the number of terms in the kinetic equation. The present study was aimed at making the method more objective. The principle is based on transforming the given relationship to one between the estimate of deviations and the number of terms, and on verifying the position of its 'equalization' statistically by means of the F test. It was shown that the kinetic equation with the number of terms established in this way can yield such a dependence of conversion α on time t which reproduces the experimental values within the framework of experimental errors. |
