• So, there's actually another way to graph it where we can directly graph the dissociation energy or the bond strengths.

    其实,还有另外一种画这个曲线的方式,可以直接画出离解能的大小,或者键的强度。

  • So what we can actually directly compare is the dissociation energy or the bond strength of nitrogen versus hydrogen.

    因此实际上我们可以直接进行比较,对氮分子与氢分子的离解能,或键的强度。

  • 22kJ/mol And dissociation energy is 122 kilojoules per mole.

    离解能大约为。

  • In contrast, the dissociation energy of a bond for hydrogen, and molecular hydrogen is everywhere around us, we see 432 kilojoules per mole.

    相反,氢分子在我们周围到处都是,一个氢分子的离解能,是432千焦每摩尔。

  • If we know that this is it the dissociation energy for a hydrogen atom, we can also say the bond strength for hydrogen molecule 424 is 424.

    如果我们知道了这是一个氢分子的离解能,那么我们也可以说氢分子的键的强度,就是。

  • And so we can actually think about how do we calculate what the dissociation energy should be for h 2, so let's go ahead and do this.

    因此,我们其实可以想到应该如何计算,氢分子的离解能,那么我们开始做一下吧。

  • It only has a dissociation energy of . 1 kilojoules per mole.

    它的离解能只有0。01千焦每摩尔。

  • Number two is dissociation energy.

    第二项是离解能。

  • So, another way to talk about dissociation energy is simply to call it bond strength, it's the same thing, they're equal to each other.

    讨论离解能的另外一种方式,是直接称它为键的强度,它们是一样的,彼此相等。

  • So, let's change our graph where we now have this zero point set as the two individuals hydrogen atoms, and then we see that our h 2 molecule is at the negative of the dissociation energy, or the negative what that bond strength is.

    那么让我们把曲线图中的零点能改到,两个分离的氢原子处,那我们就会看到,氢分子就是负的离解能,或者负的键的强度。
