) Would silver be oxidized OR red k) Base d on your answer above, write an equation showing the reaction of silver 011 MH㤠1) Combine the two reactions to get a complete reaction. Make sure out. The standard cell potential, E cll, for a reaction is: E cell E° cathode (reduction) °anode (oxidation) m) If E for copper -0.34 V and E for silver 0.80 V, what is the value of E cel 2 OKO 2. Consider the signs of Ecell a) What sign for Ecell indicates a spontaneous reaction? b) What sign for Ecell indicates a nonspontaneous reaction? c) What sign for Ecell indicates a system at equilibrium? 3. Consider the equation for the Ag/Cu reaction: Cu (s) Cuz. (aq) 2Ag" (aq) ë 2Ag (s) + + a) What is the change in Oxidation Number for Cu atom? b) How many electrons did Cu lose? c) What is the change in Oxidation Number for Ag atom? If each Ag atom gained 1 electron, how many electrons would 2 Ag atoms gain? Based on your answers to b) and d) : how many electrons were transferred between Cu and Ag? e) n 2 for the reaction above, as 2 moles of electrons were transferred. Write an expression for Q for the reaction above, between Cu and Ag, Be careful with physical states f)
