"WebMar 12, 2024 · Ecell and K are positively related so the larger the K means a more positive Ecell. Looking at the two equations E˚= (RT/nF)lnK and Ecell = E˚- (RT/nF)lnQ, you can see that if K>1 then E˚> 0. When E˚>0, then Ecell will be a greater value and will most likely be greater than zero as well. " - E and k relation
