Given below are two statements :

Statement I : The Eo value for 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 :

Multiple Choice Options

  • A Statement I is incorrect but statement II is correct
  • B Both statement I and statement II are correct
  • C Both statement I and statement II are incorrect
  • D Statement I is correct but statement II is incorrect

Step-by-Step Verified Solution

Ce4+ ⟶e− Ce3+   E° = +1.74 V

Positive SRP and higher SRP means greater oxidising power. So, Ce4+ wants to reduce to Ce3+. Indicates Ce4+ is less stable than Ce3+.
