K = 1.3 * 106 for the disproportionation reaction of Cu+ at 298 K. Calculate the E°cell and ΔG° for this reaction at 298 K
So finding delta G is actually pretty easy but for finding Ecell I'm using the equation: DeltaG= -vFE
But how do we know v is 1? When would there be a case where v would be 2 or 3...etc?
Thank you :)
