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 :
Solution
Ce<sup>4+</sup> $\buildrel {{e^ - }} \over
\longrightarrow$ Ce<sup>3+</sup> E° = +1.74 V<br><br>
Positive SRP and higher SRP means greater
oxidising power. So, Ce<sup>4+</sup> wants to reduce to Ce<sup>3+</sup>.
Indicates Ce<sup>4+</sup> is less stable than Ce<sup>3+</sup>.
