Question

Given below are two statements:

Statement I: The E° value for \[\ce{\frac{Ce^{4+}}{Ce^{3+}}}\] 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 correct answer from the options given below:

Given below are two statements:

Statement I: The E° value of Ce⁺⁴ /Ce⁺³ is +1.74 V.

Statement II: Ce is more stable in Ce⁺⁴ state than Ce⁺³ state.

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

Options

• 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.

Answer 1

Statement I is correct but statement II is incorrect.

Explanation:

Ce⁴⁺ is good oxidising agent as Ce³⁺ is more stable.

\[\ce{Ce^{4+} + e^- -> Ce^{3+}}\]; E° = 1.74 volt
