I dont know how to solve this question, there are no examples of this in my textbook so im lost =\


n = 4 and E° = 0.627v for a redox reaction with E = 1.145v. Calculate pQ. Assume T = 298.15K.

This is a simple application of the Nernst Equation

E = E⁰ - (0.5916/n) * log( [β] ^b/ [A]^a) @ 25^oC

You know E, E^o and n, solve for Q (The reaction quotient) and take the negative log of it.
