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。
This is called dissociation.
这个过程称为分离。
