The kinetic interpretation of the decomposition of calcium carbonate by use of relationships other than the Arrhenius equation

Abstract The kinetic parameters needed to describe the decomposition of calcium carbonate are obtained by a method which avoids the direct use of the Arrhenius parameters, the pre-exponential term A and the energy of activation E . It is shown that the approach is amenable to both an exact differential and integral analysis which carries certain advantages over existing methods. If needed, the method can be extended to allow the calculation of the Arrhenius parameters A and E , and in addition will show any dependence of E upon the fraction decomposed α, although it might be argued that the dependence of E is really upon the temperature.
