G°=-nFE, not covered by Chad, on DAT?

Do we see this on the DAT?
I went over Chad's videos to check, and he doesn't go over it.

I ran across a problem in Destroyer GC, Q109... I couldn't solve it using any of the equations that he laid out, so I checked the solution, and it wasn't something I had seen before.

I went over his videos, and I didn't see it either.

Anyways... if anyone has seen it on their DAT before, please let me know!

I don't think that would be on the DAT, when is your test?

Ya I had the exact same issue as you. But its not a difficult equation to remember. If anyone can chime in on pointers that would identify exactly when to know to use it, it would be much appreciated.

Well should we know it?

It's good to know it, I didn't use it personally.

Know it! It's a fair game.

Pointer: If you see a question directly asking for the Delta G of the reaction you see that it is a ReDox reaction. You know you can use the equation above.

n=mol e (calculate this based on half reactions)
F= 96500 c/mol e
E=Ered + Eox

Hope this helps.

EDIT: Note that you would also need an Ecell table to do this! And also remember that the coefficient you have in the reaction does not effect the Voltage!
