The standard enthalpy of formation (Δf298) for m ethane, CH4 is - 74.9 kJ mol-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?
  • a)
    The dissociation energy of the hydrogen molecule, H2.
  • b)
    The first four ionisation energies of carbon.
  • c)
    The dissociation energy of H2 and enthalpy of sublimation of carbon (graphite).
  • d)
    The first four ionisation energies of carbon and electron affinity of hydrogen.
Correct answer is option 'C'. Can you explain this answer?

The standard enthalpy of formation (ΔfH°298) for m ethane, C...
To calculate average enthalpy of C - H bond in methane following informations are needed
(i) dissociation energy of H2 i.e.

(ii) Sublimation energy of Cigraphite) to C(g)
C (graphite) → C (g); ΔH = y (Suppose)
Given
C (graphite) + 2H2 ( g) → CH4(g); AH = 75 kJ mol-1
