Asked by Morgan
3. An electrochemical reaction occurs between an unknown element and zinc. The half-cell reaction for the zinc is:
Zn(s) → Zn2+(aq) + 2e−
The cell potential for the reaction is Eºcell = 1.83 V.
a. Is the reaction spontaneous or nonspontaneous? Explain. (1 point)
b. What is the half-cell potential of the unknown species? (2 points)
c. What is the identity of the unknown element? (2 points)
