The species which is capable of reducingEu 3+ (aq) to Eu 2+ (aq) needs to be determined. Concept introduction: There should be positive E ° cell value in order to accomplish any reaction for the given direction. This is because for every spontaneous reaction, the value of Δ G o should be negative. The relation between Δ G o and E ° cell is represented as follows: Δ G o = − n F E ° cell For positive value of E ° cell , the value of Δ G o will be negative. The E ° cell value for a redox reaction is given by following equation. E ° cell = E ° Reduction − E ° Oxidation

Question

Chapter 19, Problem 16E

Interpretation Introduction

Interpretation:

The species which is capable of reducingEu³⁺(aq) to Eu²⁺(aq) needs to be determined.

Concept introduction:

There should be positive E°cell value in order to accomplish any reaction for the given direction. This is because for every spontaneous reaction, the value of ΔGo should be negative. The relation between ΔGo and E°cell is represented as follows:

ΔGo=−nFE°cell

For positive value of E°cell, the value of ΔGo will be negative.

The E°cell value for a redox reaction is given by following equation.

E°cell=E°Reduction−E°Oxidation
