Bond energy

  1. Jun 13, 2008 #1
    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 ???
    thanks in advance
