how do you get the enthalpy for each compound? ex: CO2 is -393.5 kj/mol where did that number come from
Experimentally Enthalpy each compound is calculated using Bomb Calorimeter.
dH = nCpdT
where dT is the change in temperature
This enthalpy is mainly combustion enthalpy from which we can calculate other enthalpy
