Detailed Solution

${Ce}^{4 +}$ is more stable than ${Ce}^{3 +}$ .It is due to the fact that the +3 oxidation state is more stable than the +4 oxidation state.

The ${Ce}^{4 +}$ ion is favored by the noble gas configuration, Because its Eo value for ${Ce}^{4 +}$ / ${Ce}^{3 +}$ is positive.

$E^{\circ} (\frac{{Ce}^{4 +}}{{Ce}^{3 +}}) = + 1.74 V$
