A reaction is at equilibrium when its forward and reverse rates are equal, right?

当正向和反向速率相等时， 反应处于平衡状态，对吗？

And when the forward and reverse reactions occur at the same rate, that's called chemical equilibrium.

当正向和反向反应以相同的速率发生时， 这就是所谓的化学平衡。

If we write these two terms together to show that the forward and reverse rates are equal, like in equilibrium, and solve for a single constant, we get something that looks very much like an equilibrium expression.

如果我们将这两项写在一起以表明正向和反向速率相等，就像在平衡状态下一样，并求解一个常数，我们会得到一个看起来非常像平衡表达式的东西。
