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

现在我们将这些数字应用到平衡常数的公。

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

学家不仅知道一个反应的平衡常数，还知道每种反应物有多少可用。

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——至少我这样希望，像盐酸或硝酸，电离程度很强。

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

你学会了如何计算平衡常数，Keq。

And so we can figure out its acid ionization constant, which is essentially an equilibrium constant.

这样我们就可以算出它的酸离子常数，它本质上是一个平衡常数。

It's going to have its own equilibrium constant.

它将有自己的平衡常数。

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.

学习了如何计算平衡常数 Keq。学会了如何通过了解反应的初始条件来计算反应的平衡条件。

Remember that's based on the equilibrium constant.

请记住，这是基于平衡常数。

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.

这些平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。

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

平衡常数很容易设置，但很难解释，所以我们先用一个显然虚构的学方程来举个例子。

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

因此， 平衡常数仅适用于特定温度。

And so in this equilibrium constant of water we can essentially ignore water.

因此，在这个水的平衡常数我们基本上可以忽略水。

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.

平衡常数或Keq等于产物的摩尔浓度的乘积除以反应物的摩尔浓度的乘积。

And so we could also use the equilibrium constant of the base.

因此我们也可以使用碱的平衡常数。

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

实际上有一种方法可以根据测得的电压确定平衡常数， 反之亦然。

Well the equilibrium constant is going to help there as well.

那么平衡常数也会起到帮助作用。

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

需要进行平衡计算的第一件也是最重要的事情是平衡常数。

Remember that equilibrium constant is simply the products or the concentration of the products divided by the concentration of the reactants.

请记住，平衡常数只是产物或产物的浓度除以反应物的浓度。

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

现在我要在这里指出， 氧还原反应的电势与其平衡常数有关。

It's on free energy and the equilibrium constant.

它与自由能和平衡常数有关。
