but now, it「s not as a function of the composition at the liquid phase it」s a function of the composition in the gas phase.
但是现在,这里不再是以液相的组分比,作为变量,而是以气相的组分比作为变量。
but i「ve got more material in the liquid phase to collect.
我们已经在液相中收集到了更多的组分。
we started out with four variables; the temperature, the pressure, and the components in the composition in the liquid phase and the composition in the gas phase.
我们一开始有四个变量:,温度,压强,某个组分在液体中的比例,和它在气体中的比例。
and we squeeze, and now we」ve got more water in the liquid phase than in the gas phase.
我们继续压缩,现在液态的水,比气态的水更多。
and the liquid phase obeys raoult「s law.
液相遵循拉乌尔定律。
now i」ve transferred material from the liquid phase to the gas phase.
我已经,把液体变成了气体。
since the gas and liquid are in equilibrium, therefore we know the chemical potential in the liquid phase too.
由于气相和液相的化学势相等,因此我们也就知道了,液相中的化学势。
ok. then you started looking at both the gas and the liquid phase in the same diagram.
好,然后在同一张图中,考虑气相和液相。
we're going to start with the chemical potential equal of the liquid phase is equal to the chemical potential of the gas phase. for the solvent at equilibrium.
