Ra?e constants for the reaction of 0(3P) atoms with CaH4, CaHB and NO(M = NpO) have been measured over the temperature range 300-392Β°K using a modulation-phase shifi technique. The Arrhenius expressions obtained are: C2H4, k2 = 3.37 X 10' exp[-(1270 -f 200)/RT] liter mole-' see-', CJH~, kz = 2.08 x
Standard Gibbs free energies of formation (AIG ~ for the minerals rhodonite (MnSiO3), tephroite (Mn2SiO4) and braunite (MnySiO12) have been determined by measuring the oxygen fugacities of the following redox equilibria: The measurements were performed by means of the solid-state emf technique invo
