So we go back to writing what the Gibbs free energy is.
我们回到吉布斯自由能的表达式。
The Gibbs free energy per mole of a in the liquid phase.
液相中的化学势就是，液相中每摩尔a的吉布斯自由能。
Per mole, which is just the Gibbs free energy of vaporization.
每摩尔·吉布斯自由能，就是汽化的吉布斯自由能。
Now, the chemical potential, as we saw, was the Gibbs free energy.
现在，化学势，就像我们看到的，等于吉布斯自由能。
The Gibbs free energy. Notice, we could also write, let's rewrite that.
吉布斯自由能，注意，我们还可以这样写，重写一下。
