(a) Each reaction between zinc and copper generated 1.10 V. Two Zn/Cu piles were stacked together in the experiment. This produced a total of 2.11 V. When the half cells are combined end-to-end, it appears that the total voltage is the sum of each half cell. This is consistent with the fact that when batteries are connected in series, the total voltage is also the sum of each individual voltage. (b) The voltages of the galvanic cells were effected slightly by varying concentration. When the concentration of the products was greater than the concentration of the reactants, the equilibrium was shifted to the left, resulting in a drop in voltage. When the concentration of the reactants was greater, there was an increase in voltage. This is due to the last term in the Nernst
