And you learned about the equilibrium constant for that reaction, which has a special name: the water dissociation constant.

你不太可能碰到它们——至少我样希望，像盐酸或硝酸，电离程度很强。

You've learned how to calculate an equilibrium constant, Keq.

您已经学习了如何计算衡常数 Keq。

There's actually a way to determine the equilibrium constant from a measured voltage, and vice versa.

实际上有一方法可以根据测得的电衡常数， 反之亦然。

Therefore, the equilibrium constant is only true for a specific temperature.

因此， 衡常数仅适用于特温度。

The symbol for this kind of equilibrium constant is Ka, for an acid, or Kb for a base.

衡常数的符号是​​ Ka（酸）或 Kb（碱）。

Fortunately for us, chemists have already figured out the equilibrium constants for most common reactions.

对我们来说幸运的是， 化学家已经计算出大多数常见反应的衡常数。

Now I gotta point out here that the electrical potential of a redox reaction is related to its equilibrium constant.

现在我要在里指出， 氧化还原反应的电势与其衡常数有关。

The first and most important thing you need to do equilibrium calculations is the equilibrium constant.

您需要进行衡计算的第一件也是最重要的事情是衡常数。

Now we apply these figures to our formula for the equilibrium constant.

现在我们将些数字应用到衡常数的公式中。

Chemists often know not only the equilibrium constant for a reaction, but also how much of each reactant is available.

化学家通常不仅知道反应的衡常数，而且知道每反应物的可用量。

Equilibrium constants are easy to set up but hard to explain, so let's start with an example using this obviously fake chemical equation.

衡常数很容易建立，但很难解释，所以让我们从一个例子开始，使用个明显虚假的化学方程式。

You've learned how to calculate an equilibrium constant, Keq. You've learned how to calculate the equilibrium conditions of reactions just from knowing their initial conditions.

您已经学习了如何计算衡常数 Keq。您已经学会了如何通过了解反应的初始条件来计算反应的衡条件。

These equilibrium constant equations and the constants themselves are one of the few places where you don't need to write them with every number.

些衡常数方程和常数本身是少数几个不需要用每个数字都写出来的地方之一。

The equilibrium constant, or Keq, is equal to the product of the molar concentration of the products divided by the product of the molar concentration of the reactants.

衡常数或 Keq 等于产物的摩尔浓度除以反应物摩尔浓度的乘积。
