How do calculate the energy needed to break all the bonds in 1 mol of methane?
The standard molar enthalpy change of bond dissociation (DHd° is the energy change when 1 mole of bonds is broken, the molecules and resulting fragments being in the gaseous state at 298K and a pressure of 100kPa. IntroductionThis energy refers to a specific bond in a molecule, but if a molecule has 4 of the same bond (eg the C-H bonds in methane), then different dissociation energies can occur.CH4(g) => CH3(g) + H(g) DHd° = +427 kJ mol-1CH3(g) => CH2(g) + H(g) DHd° = +371 kJ mol-1So it is much more useful to know the average amount of energy needed to break a particular bond. In this case, the process of breaking all the bonds in methane ending up with gaseous atoms.So this process could be written as:The enthalpy change for this reaction is +1646 kJ mol-1 , so the average bond enthalpy is +1646 / 4 = +412 kJ mol-1 . They can be looked up in data tables.It is important to stress that these are mean or average bond enthalpies. If Average bond enthalpies are used to calculate an enthalpy change, the answer will be slightly out compared to a result obtained by other methods.-----------------------------------------------------------------------------------------------------So if you are talking about the Mastering chem question, here is the answer.dissociation energy of C-H bond is 410 kJ/mol and there are 4 mols of C-H bond in 1 mol of CH4so 410kJ/mol *4 = 1640 KJ/mol
