Hi just a little confused two questions: 1) what happens when an electrode mass of a voltaic cell is increased does it affect anything in the cell i don't mean how mass increases at the cathode, i mean, if i were to have two voltaic cells that were exactly the same except the mass of the cathode in one was twice the size of the cathode of. Standard electrode potentials in an effects of different temperatures and concentrations may be tracked in terms of the gibbs free energy change δg this free. Similarly, the her current also increases, confirming that the hydrogen electrode reactions are temperature activated processes, in agreement with the previous studies [12,14,18,20] the cathodic potential scans displayed in fig 2a for non-activated ni electrode reveal also an abrupt increase of the hor current just after the onset of the reduction of ni oxide species formed at positive potentials.Download
