A gaseous hydrocarbon reacts completely with oxygen gas to form carbon dioxide and water vapor. Given the following data, determine ?H°f for the hydrocarbon:
PH°rxn = -2044.5 kJ/mol hydrocarbonPH°f (CO2) = -393.5 kJ/molPH°f (H2O) = -242 kJ/mol
Density of CO2 and H2O product mixture at 1.00 atm, 200.°C is 0.751 g/L.
The density of the hydrocarbon is less than the density of Kr at the same conditions.
