The E ° value for Ce 4+ / Ce 3+ is +1.74 V because the most stable oxidation state of lanthanide series elements is +3. It means Ce 3+ is more stable than Ce 4+.

Q. Given below are two statements:
Statement I : The $E^{\circ}$ value of $C e^{4 +} / C e^{3 +}$ is $+ 1.74 V$
Statement II : Ce is more stable in $C e^{4 +}$ state than $C e^{3 +}$ state.
In the light of the above statements, choose the most appropriate answer from the options given below:

Both statement I and statement II are correct

Statement I is incorrect but statement II is correct

Both statement I and statement II are incorrect

Statement I is correct but statement II is incorrect

The $E^{\circ}$ value for $C e^{4 +} / C e^{3 +}$ is $+ 1.74 V$ because the most stable oxidation state of lanthanide series elements is $+ 3$ .
It means $C e^{3 +}$ is more stable than $C e^{4 +}$ .
