Now recall that at 25°C, kW=1.0×10-14. This is a value you'll have to remember on your own. You're not going to be expected to be given a formula sheet with this value present. But remember, kW is an equilibrium constant and like the other equilibrium constant, it is temperature dependent.

If I play around with my temperature where it strays away from 25°C, then the value itself will change. We're going to say the general trend is as the temperature increases, our kW increases. If we take a look here, we have temperatures ranging from 0°C all the way up to 100°C. And if you look you can see that as our temperature starts to increase, going from zero to 100, we can see that the general trend is that my kW value is increasing.

Again at 25°C, kW is equal to this value. This is what you're expected to remember on your own. If the temperature changes from 25°C, you'll be given that new value for kW because it could really be any number. So it's hard for you to memorize an entire list of kW at all these different temperatures, OK? And remember the general trend is as the temperature increases, our kW generally increases as well.
