### Nerst Equation

Do we need to know how to derive the Nerst Equation or will it be given to us?

The nerst equation is on the equation sheet given.

In a review session, one of the TAs said lavelle would never ask us to derive an equation.

You will not need to know how to derive it.

It's the equation E = E° - (RT/nF) lnQ ^^ the one mentioned today!

No, but you can see it on the equation sheet.

### Re: Nerst Equation

I don't think we ever need to know how to derive any of the equations Lavelle shows us in lecture, it's more to help us with a conceptual understanding. You just need to know the equation itself and when it's used.

### Re: Nerst Equation

if you're ever concerned, just check out the constants and equations sheet on lavelle's site. It's been the same since the course started and contains all the equations that will be given to us

### Re: Nerst Equation

I think it’s always helpful to know how to derive the equation because once you are able to do that, you know you have a proper grasp of the concepts. However, we are not expected to do this on an exam!

### Re: Nerst Equation

As many already mentioned, the equation is given but knowing how it was derived can help understand it better. So if you are given steps of the derivation then you will know how to manipulate the problem to get what you need.
