An electrochemical cell utilizes the following redox reaction NHa * (ag) + 8Ce4"(ag) + зн-0() > NO; (ag) + 8Ce3"(ag) + 10н* (ag) Where the relevant half-reactions are: NO3 - (ag) + 1OH+ (ag) + 8e- → NH4 + (ag) + 3H20 Ce**(ag) + e- > Ce3*(ag) Ecel = +0.88 V Ecel = +1.72 V 1. Calculate Ec(not under standard conditions) when [NH4 +1 = 0.35 M, [Ce**] = 0.25 M, [NO3 -1= 5.0 x10-2 M, [Ce3+] = 6.0 ×10-2 M, and the [H*] = 1.0 x10-3 M 2. How is Ecel, impacted when the concentration of H* (ag) is reduced? In other words, what happens when the pH decreases? Provide reasoning to support your answer.

A.  From the reaction as shown below, calculate the Standard Cell Potential of a Galvanic Cell that uses the half-reactions shown below.                              Cr3+    +    3e-    ------->     Cr               Eo = -0.73 V                             Al3+    +    3e-    ------->     Al              Eo = -1.66 V B. A galvanic cell is made using 0.25M ZnSO4 and an unknown amount of CuSO4. The cell potential is 105V at 50oC. What is the concentration of CuSO4 in the cathode compartment?         Zn(s)   +   Cu(aq)2+   ------->   Zn(aq)2+   +   Cu(s)          Eo = 1.10 V Use:E = Eo - (RT/nF) + lnQ
