APPENDIXThe molecular-dynamic results of Alder are given in a form where the Holmholtz energy is the sum of a hard-sphere part and a perturbation part; the latter follows from attractive intermolecular forces. These are represented by a square-well potential where the width of the well is a fixed multiple ( H ) of the hard-sphere diameter. For the hard-sphere part we use the Carnahan-Starling equation. For the perturbation part we use Alder's results:
The dimensionless constantsA, are n = l , M = 6 n = 2 , M = 9 n = 3 , M = 5 n = 4 , M = 4 A43 = -0.41246808 X 10' When For methane the effect of temperature on vbsp is given by ---~' s p where subscript sp (specific) indicates that u' is per gram.in an Argon Plasma A reactor system was developed for the study of heterogeneous reaction kinetics in plasma tail flames. This system was used to investigate the thermal decomposition kinetics of stationary particles of molybdenum disulfide in both the molten and solid state when exposed to argon flames in the temperature range 3 OOOOK to 8 00O0K.In the solid state a shrinking-core reaction model was obeyed. The rate of reaction was largely controlled by the diffusion of sulfur vapor outwards through the product layer. An apparent activation energy of 134
