1. Calculate the work (in kJ) when 1.80 moles of methane react with excess oxygen at 425 K:

CH4(g) + 2O2(g) → CO2(g) + 2H2O(l)

2. Using the technique of the previous problem ΔE was found to be -2,000.00 kJ/mol of an unknown liquid hydrocarbon at 298 K. In another experiment it was determined that for each mole of hydrocarbon, 5 moles of oxygen gas are consumed and 9 moles of CO2 gas and 4 moles of H2O liquid are produced. Find ΔH per mole of this hydrocarbon (in kJ) at 298 K.
