The standard enthalpy of formation (ΔfH\(^{\circ}_{298}\)) for methane, CH\(_4\) is \(-74.9\mathrm{kJmol}^{-1}\). In order to calculate the average energy given out in the formation of a C-H bond from this it is necessary to know which one of the following?
Choose Your Option
A. The dissociation energy of the hydrogen molecule, H\(_2\)
B. The first four ionisation energies of carbon.
C. The dissociation energy of H\(_2\) and enthalpy of sublimation of carbon (graphite).
D. The first four ionisation energies of carbon and electron affinity of hydrogen.
