Question

Calculate the bond energy per mole for breaking all the bonds in methane

Answer 1

Answer : The required bond energy per mole for breaking all the bonds in methane is, 1656 kJ/mol

Explanation :

The given compound is,
`CH_4`.

Methane compound breakdown into 4 C-H bonds.

Given:

`B.E_(C-H)` = 414 kJ/mol

The expression will be:

`\Delta H_(CH_4)=4* (B.E_(C-H))`

`\Delta H_(CH_4)=4* (414kJ/mol)`

`\Delta H_(CH_4)=1656kJ/mol`

Therefore, the required bond energy per mole for breaking all the bonds in methane is, 1656 kJ/mol
