Solid state reaction kinetics: Structure of the simplest rate-time curve in terms of random tessellations

The simplest within the geometric-probabilistic approach rate-time curve is specified and its structure is made explicit in terms of random tessellations. The validity of using the notion of typical cell in this context is verified via direct simulation, and a new description of rate-time curves is suggested. In comparison with the conventional approach this provides a greater scope for exploring chemical regularities of solid state reactions.
