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

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.
