THE REDUCTIVE DECOMPOSITION OF SULPHATE-I. KINETICS OF THE APPARENT REACTION CALCIUM SOLID-SOLID

the fractional degree of production and the initial composition of the reactants. One of the principal assumptions of the model is the presence of a liquid phase formed by mixtures of CaS and CaSO,. Fractional production rates calculared after determining the required model parameters (kinetic constants and volume plus composition of the liquid phase) show close agreement with experimentally obtained values. 1.
