A gaseous hydrocarbon reacts completely with oxygen gas to, Ask an Expert

Academics

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 hydrocarbon
PH°f (CO2) = -393.5 kJ/mol
PH°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.
