1. The problem statement, all variables and given/known data

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

3. 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?

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.

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 ???
