同样的，如果我们观察二价的氟，它是每摩尔160焦。
Likewise, if we look at fluorine in its diatomic molecule, it is 160 kilojoules per mole.
所以你们可以看每摩尔的这个反应。
它的离解能只有0。01千焦每摩尔。
It only has a dissociation energy of. 1 kilojoules per mole.
这证明有每摩尔435焦的，的共价能。
And this turns out to have a bond strength of 435 kilojoules per mole.
即单个分子的气体常数，而不是每摩尔的。
这是每电荷库伦,这是每摩尔库伦。
它是每摩尔569焦。
所以你们可以看每摩尔的这个反应。
每摩尔物质的体积。
本质上我们不会看到它，它等于9千焦每摩尔。
Essentially we're not going to see this, it's 9 kilojoules per mole.
它不是克每摩尔。
每摩尔·吉布斯自由能，就是汽化的吉布斯自由能。
Per mole, which is just the Gibbs free energy of vaporization.
如果我们求摩尔质量的话，我们的结果是907克每摩尔。
And if we solve for molecular weight, then we wind up with 907 grams per mole.
除以18克每摩尔加上10克，除以溶质的摩尔质量。
Divided by 18 grams per mole plus 10 grams divided by the molecular weight in grams per mole.
这是12。011克每摩尔,或者12。011原子质量单位。
This is 12.011 grams per mole or 12.011 atomic mass units,AMU.
液相中的化学势就是，液相中每摩尔a的吉布斯自由能。
气相中的化学势，就是气相中每摩尔a的吉布斯自由能。
And this is just the Gibbs free energy per mole of a in the gas phase.
这样做之后，对于K常量你就能得到2,1。312百万焦耳每摩尔。
And if you do so, you will end up with 1.312 mega joules per mole for this quantity K.
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 if I tell you that the energy for single hydrogen atom is negative 13 12 kilojoules per mole.
这意味为了完成上面的反应，我们不得不往里面注入，7，千焦每摩尔的能量。
This means in order to do that we actually have to put 7 kilojoules per mole of energy into the reaction to make it happen.
我是在整个价电子的集合上作平均，最后得到1。91兆焦每摩尔。
I'm averaging it over the entire set of valence electrons which gives me 1.91 MJ 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。
In contrast, the dissociation energy of a bond for hydrogen, and molecular hydrogen is everywhere around us, we see 432 kilojoules per mole.
焦耳每个原子，或者，如果乘以，阿伏伽德罗常数你会得到焦耳数每摩尔。
It is joules per atom. Or, if you multiply by Avogadro's number then you will get joules per mole.
我们知道它的值是多少，它就是我们在这见到过的负，424，千焦每摩尔。
So we know what that number would be, it would be negative 424 kilojoules per mole that we see here.
既然KrF2的原子化热只有23千卡每摩尔，这意味着ArF2不能被制备。
Since the heat of atomization of KrF2 is only 23 kcal per mol, this implies that ArF2 cannot be made.
现在我们看这一项，他等于10克除以溶质的分子量，即克每摩尔，再除以1000克水。
So, now we have this, it's 10 grams divided by the molecular weight, which is in grams per mole, over 1000 grams of water.
比如，以氯为例，我们可以说氯的电子亲和能，应该等于正的，349，千焦每摩尔。
So, for example, for the chlorine case, we would say that the electron affinity for chlorine is actually positive 349 kilojoules per mole.
因此这并不是一个容易发生的过程，我们会发现氮的电子亲和能，应该是负的，7，千焦每摩尔。
So this is not going to be a favorable process, we're going to find that the electron affinity is actually a negative 7 kilojoules per mole for nitrogen.
