Kinetics of thermal decomposition of the solid state II. Delimiting the homogeneous-reaction model

Present evidence shows that many thermal processes can be described by the generalized rate equation

−dx/dt = Z exp(E*/RT)f(x) but many others cannot. Still others may be adequately describable by a modified equation. A small set of tests will enable the experimenter to determine whether or not the equation applies. These include change of sample size, change of sample geometry, and extended time of reaction.
