Which is the correct representation for the Nernst equation?

The Nernst equation can be written as:

1. \(E_{RP} = E^0_{RP} + \frac{0.059}{n}log\frac{[Oxidant]}{[Reductant]}\)
2. \(E_{OP} = E^0_{OP} + \frac{0.059}{n}log\frac{[Oxidant]}{[Reductant]}\)
3. \(E_{OP} = E^0_{OP} + \frac{0.059}{n}log\frac{[Reductant]}{[Oxidant]}\)

So the correct answer is (4) All
