Answer : The required bond energy per mole for breaking all the bonds in methane is, 1656 kJ/mol
Explanation :
The given compound is, [tex]CH_4[/tex].
Methane compound breakdown into 4 C-H bonds.
Given:
[tex]B.E_{C-H}[/tex] = 414 kJ/mol
The expression will be:
[tex]\Delta H_{CH_4}=4\times (B.E_{C-H})[/tex]
[tex]\Delta H_{CH_4}=4\times (414kJ/mol)[/tex]
[tex]\Delta H_{CH_4}=1656kJ/mol[/tex]
Therefore, the required bond energy per mole for breaking all the bonds in methane is, 1656 kJ/mol
