Fig. 3. Thermogravimetric analysis of W(CO)6: (A) precursor TG trace at a constant temperature ramp rate of 10 °C min−1; (B) the Arrhenius plot (Ea is obtained from the slope of the curves via –Ea/R); (C) plot of ln p vs. 1/T, the enthalpy of sublimation is derived from the slope of the straight lines, which is equal to –ΔHsub/R; (D) plot of ln(1/Torr) vs. T, used to extrapolate the 1 Torr temperature. R = ideal gas constant 8.314 J K−1 mol−1 (p = kPa).
