The initial voltage of this cell is...

Question 4 options:
a. 0.00 V
b. -1.37 V
c. +1.63 V
d. -1.63 V
e. +1.37 V

Answer :

Final answer:

To figure out the initial voltage of an electrochemical cell, you use the cell potential equation E cell= Eᵒcathode - E°anode, using the standard electrode potentials for the cathode and anode substances.

None of the option is correct.

Explanation:

The question pertains to the determination of the initial voltage of an electrochemical cell. To calculate cell potential (Ecell), one must consider the standard electrode potentials (E°) of the two half-reactions involved. The relevant formula is E cell= Eᵒcathode - E°anode.

Oxidation occurs at the anode and reduction occurs at the cathode. If given standard half-cell potentials for the cathode and anode substances, one can plug these values into the equation to find the cell's voltage or Ecell. If the calculated Ecell is positive, the reaction is spontaneous; if it is negative, the reaction is non-spontaneous.

In your case, since specific half-cell potentials are not given, it is not possible to provide the initial voltage without additional information. Generally, the standard cell potential equals the difference between the standard reduction potentials of the cathode and anode.

For example, if you had a cathode with a reduction potential of +1.229 V and an anode with a reduction potential of -0.117 V (when reversed for oxidation), the initial voltage would be 1.229 V - (-0.117 V) = +1.346 V.

None of the option is correct.
