Question

Given 2Ce4+ + Co → 2Ce3+ + Co2+, E° = 1.89 V.
The standard reduction potential for Co2+ is
-0.28 V. The standard reduction potential of Ce4+ to
Ce3+ is
(1) -1.61 V
(2) 1.61 V
(3) 2.17 V
(4) -2.17 V​

Answer 1

Answer:

volt

.............

....

Answer 2

Answer:1.61 v

Explanation:Ce^+4 to Ce^3+ gets reduced

So,E^⁰cell=E^⁰cathode ‐E^⁰anode

1.89 =E^⁰cathode -(-0.28)

E^⁰cathode=1.61 v
