随着时间的推移，这两者必须重新达到平衡。

Over time, those have to come back in balance.

你可以设想在初始的很快，达到平衡的过程以后的任何时间。

You can assume that at any time after the initial very fast process of getting equilibrium.

那么如果你把它作为时间的函数画出来，最终你会达到浓度A平衡。

So if you were to sketch it out as a function of time, eventually you'll get to the concentration a equilibrium.
