## Calculate K at 25°C for each of the reactions referred to in Question 32. Assume smallest whole-number coefficients.

Interpretation Introduction

(a)

Interpretation:

The value of K for the given cell reaction containing chromium and tin ions needs to be determined.

Concept introduction:

The standard electrode potential of a cell denoted by E° is the electrode potential of the cell measured under standard conditions in volts. The standard Gibbs free energy of a system is the change in the free energy of the system measured under standard conditions of 1 atm pressure and 298 Kelvin temperature.

### Explanation of Solution

The value of E° of the cell is 0.562V.

The relation between ΔG° and E° of the cell is given by the following equation:

ΔGο=-nFEcellο

Here F is the Faradays constant whose value is 96500C/mole e-

And n is given to be 2 mole e-

Substituting all the values in this equation:

ΔGο=-nFEcellοΔGο=-2mole e-×96500C/mole e-×0.562VΔGο=-108466JΔGο=-108

Interpretation Introduction

(b)

Interpretation:

The value of K for the given cell reaction containing manganese ion and hydrogen peroxide needs to be determined.

Concept introduction:

The standard electrode potential of a cell denoted by E° is the electrode potential of the cell measured under standard conditions in volts. The standard Gibbs free energy of a system is the change in the free energy of the system measured under standard conditions of 1 atm pressure and 298 Kelvin temperature.
