Complete dissociation of particles with a given shape, but of differing sizes has been found to follow a common curve. Figure 3 shows such a curve for spheres of a dense limestone, and the results are summarized in Table 1. Figure 4 and Table 2 summarize the combined effects of temperature and size on spheres of the same dense limestone.
