Given below are two statements :
Statement I : The $E °$ value of ${Ce}^{4 +} / {Ce}^{3 +}$ is $+ 1 . 74V$
Statement II : Ce is more stable in ${Ce}^{4 +}$ state than ${Ce}^{3 +}$ state.
In the light of the above statements, choose the most appropriate answer from the options given below:

Question

Given below are two statements :

Statement I : The $E °$ value of ${Ce}^{4 +} / {Ce}^{3 +}$ is $+ 1 . 74V$

Statement II : Ce is more stable in ${Ce}^{4 +}$ state than ${Ce}^{3 +}$ state.

In the light of the above statements, choose the most appropriate answer from the options given below:

Quantrex Academy · Accepted Answer

Correct answer: D. Statement I is correct but statement II is incorrect

The E ° value for Ce ^ 4 + / Ce ^ 3 + is + 1 . 74V because the most stable oxidation state of lanthanide series elements is + 3 . It means Ce ^ 3 + is more stable than Ce ^ 4 + .
