APPLICATION OF DIFFERENTIAL THERMAL ANALYSIS TO THE DISSOCIATION OF MnO2 AND Mn2O3
Keyword(s):
The method of differential thermal analysis was employed to determine the oxygen pressures produced by the reactions[Formula: see text]and[Formula: see text]in the temperature range 250–1000 °C. The heats of reaction calculated from the slope of the van't Hoff curves are: ΔH835°K0 = 25.8 ± 1.5 and ΔH1200°K0 = 25.3 ± 4.2 kcal per mole of oxygen. These are in agreement with previously reported values based on equilibrium measurements, but are lower than those determined by calorimetry.
