Question

The standard enthalpy of combustion of n-propane is -2220 kJ mol$^{-1}$ at 25$^\circ$C. From this information and enthalpy of formation data for CO$_2$(g) and H$_2$O(g), calculate the enthalpy of formation of n-propane. The enthalpy of formation of propene is +20.42 kJ mol$^{-1}$. Calculate the enthalpy of hydrogenation of propene to propane.
