Using the delta Hf^degree, S^degree and delta Gf^degree data from Appendix D in your textbook, calculate delta H degree, delta S degree and delta G^degree for the following reaction. Show that delta G^degree= delta H^degree - (T)(delta S^degree). Indicate whether the reaction is spontaneous or not.
Calculate the mole fraction and partial pressure of each gas, and the total pressure in the tank. a) Boron trifluoride - mole ratio - partial pressure b) Sulfur hexafluoride -mole ratio -partial pressure
Determine ΔHreaction° for: 4H2O (l) + 2 NH3 (g) → 2NO2 (g) + 7H2 (g) using the following two equations: (1) N2 (g) + 3H2 (g) → 2 NH3 (g) ΔH1° = -184 kJ (2) 4NO2 (g) + 8H2 (g) → 2 N2 (g) + 8 H2O (l) ΔH2° = -196 kJ
