Question

2. You want to make a battery that produces between 0.7 and 0.8 V. You have Ag, Cu, Fe, and Zn metals and their corresponding 1 M metal ion solutions. Ag te ->Ag Cu+ 2 e --> Cu reduction0.80 V reduction0.34 V reduction 0.45 V reduction-0.76 V Fe +2 e -> Fe e. Your battery works (of course!) and produces between 0.7 V and 0.8 V like you predicted. But your electronic device needs iust a bit more voltage from your battery to work. Which change increases the voltage of your battery the most? (Hint: use Nernst equation.) increase the battery temperature to 60oC from 25oC decrease the battery temperature to OoC from 25oC increase the concentration of both O solutions to 10 M from 1 M (T still at 250C) increase concentration of anode solution to 10 M from 1 M and keep the concentration of the cathode solution at 1 M (T still at 250C) increase concentration of cathode solution to 1O M from 1 M and keep the concentration of the anode solution at 1 M (T still at 250C)
