Another example of an effect of magnetic properties on reactivity was found in the oxidation of Fe304 to Fe203 [127], The Arrhenius plot of the rate data showed no significant change in slope well below and well above the Curie temperature (578°C). In the temperature range from 560 to 640°C, however, an anomalous deviation (a maximum and a minimum on log k), known as the Hedvall effect [128], was observed. No satisfactory explanation has yet been given.

Figure 8 Assumed first-order Arrhenius Plot for oxidation of several model organic compounds in supercritical water, showing relative ease or difficulty of destruction. The band denoted as Tresidence represents a typical time scale that can be investigated in a lab-based SCWO system. Note that the ordinate is the base ten logarithm and K represents the assumed first order rate constant. (From Refs. 51-57.)...
