Calculate the bond dissociation energy for the breaking of all the bonds in a mole of methane

Answer : The bond dissociation energy is 1656 kJ/mol

Explanation :

In methane, the energy required to break the one C-H bond is 414 kJ/mol.

Now we have to determine the bond dissociation energy for the breaking of all the bonds in a mole of methane.

The formula of methane is,

In methane, there are 4 number of C-H bonds. So, the bond dissociation energy will be:

Now put the value of bond energy of C-H bond in this expression, we get:

Hence, the bond dissociation energy is 1656 kJ/mol

the answer is a for sure mark brainliest i had got this right on usatestprep
