Given below are two statements : Statement I : The E ° value of Ce 4 + / Ce 3 + is + 1 . 74   V…

Given below are two statements :

Statement I : The E° value of Ce4+/Ce3+ is +1.74 V

Statement II : Ce is more stable in Ce4+ state than Ce3+ state.

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

  1. Both statement I and statement II are correct
  2. Statement I is incorrect but statement II is correct
  3. Both statement I and statement II are incorrect
  4. Statement I is correct but statement II is incorrect

Solution

The E° value for Ce4+/Ce3+ is +1.74 V because the most stable oxidation state of lanthanide series elements is +3.

It means Ce3+ is more stable than Ce4+.
