通常人们把拆开\(\rm{1}\)\(\rm{mol}\)某化学键所吸收的能量看成该化学键的键能\(\rm{.}\)键能的大小可用于估算化学反应的反应热\(\rm{(\triangle H)}\)．
化学键 | \(\rm{C}\)\(\rm{l}\)\(\rm{-C}\)\(\rm{l}\) | \(\rm{H-H}\) | \(\rm{H-C}\)\(\rm{l}\) | \(\rm{N≡N}\) |
键能\(\rm{/}\)\(\rm{k}\)\(\rm{J⋅}\)\(\rm{mol}\) | \(\rm{243}\) | \(\rm{436}\) | \(\rm{431}\) | \(\rm{946}\) |
