So if I tell you that the energy for single hydrogen atom is negative 13 12 kilojoules per mole.
如果我告诉大家单个氢原子的能量,是负的,1312,千焦每摩尔。
So, what we get for the disassociation energy for a hydrogen atom is 424 kilojoules per mole.
因此,我们就得到了氢原子,离解能的大小为,424,千焦每摩尔。
You plug all of this in and you get 344 kilojoules per mole, which then sums to 608.
把这些都算上,我们得到344千焦每摩,与上面结果加起来是608千焦每摩。
