Calculating Average C-H Bond Energy in Methane

[Kushal]

Homework Statement

by means of a balanced equation, including state symbols, illustrate the term the average C-H bond energy in methane.

The Attempt at a Solution

i know what that all the C-H bonds in methane are not the same, and the mean of these bond energies give the average bond energy. but what equation i am supposed to write?

 

[Ed Aboud]

Well the mean bond energy for methane is 1/4 the enthalpy for the reaction

CH4(g) -> C(g) + 4H(g)

I'm not sure if that helps you with your question.

 

[Kushal]

yeah that makes sense!

thnks

hello ,
Can we calculate the total bonding energy of methane molecule if we know the total energies of ch4 , c and h (calculated using DFT)if yes then ho ?
thanks in advance
