How does the spontaneity of the process below depend on temperature? PCI5(9)+H2O(g)POCI3(g) +2HCI(g) -126 kJ mol1, AS = 146 J K-'mol1 ΔΗ Select the correct answer below: nonspontaneous at all temperatures spontaneous at all temperatures spontaneous at high temperatures and nonspontaneous at low temperatures spontaneous at low temperatures and nonspontaneous at high temperatures
Free Energy of Reaction -- Temperature Dependence eu. 1000°C 2NH3(g) + 302(g) + 2CH4(9) DIDA → 2HCN(9) + 6H20(9) The above reaction is used in the industrial production of hydrogen cyanide. Consider the relevant thermodynamic data from the appendices of your text. (The tabulated values AHºf and sº are for 25°C. For the purposes of this question assume that AH° and ASº are invariant with temperature. This is not actually true but would generally be a reasonable approximation over "small"...
