Abstract: | Chemical Transport of FeP2 and FeP4 with Iodine Experiments on the chemical transport of FeP2 and FeP4 with iodine are discussed, considering the gaseous molecules I1, I2, FeI2, Fe2I4, FeI3, Fe2I6, PI3, P2I4, P4, P2, and P. Thermodynamic calculations give δH°(298) = 56.322 kcal and ΔS°(298) = 39.5 cal/K for the reaction FeP2,f + I2 = FeI2 + 0.5 P4 and δG°(923) = 35.8 kcal for the reaction FeP4,f + I2 = FeI2 + P4. |
