### Ecell

Ecell = Eocell - (RT/nF) ln Q and Ecell = Eocell - (0.0592/n) log Q both give Ecell. However, why are both given? Why couldn't you just use one or another? What's the point of having both?

I belive it’s just one of them is more specific to 25 degrees Celsius (the second one)

the E0 always refers to standard conditions, I believe at equilibrium as well.

### Re: Ecell

Two are given since one refers to standard conditions, 25 degrees C and 1 atm while the other can refer to any condition separate from standard.
