For the reaction H2(g) + 1/2O2(g) --> H2O(g) the heat of formation of H2O(g) at 298 K is -241.8 kJ/mol. If 1.4756 moles of H2(g) and 6.6495 moles of O2(g), initially at 298 K, are ignited in an adiabatic constant pressure (P=1 bar) vessel calculate the final temperature of the gas mixture. Assume the heat capacities of the gases are constant and are given in Appendix B of your text.
