Chapter 19, Problem 19P

Interpretation Introduction

Interpretation:

The values of $\Delta E°\text{'}$ and $\Delta G°\text{'}$ for the reduction of ${\text{NADP}}^{+}$ by ferredoxin are to be calculated.

Concept introduction:

Gibbs free energy is a thermodynamic term that is used to find out the spontaneity of the reaction. It is used to calculate the maximum reversible work for a system at constant pressure and temperature. It is related to enthalpy and entropy of the reaction. Along with that it is also related to cell potential of the cell.

The standard free energy of a redox reaction depends on the standard cell potential of the reaction. The standard free energy also depends on the equilibrium constant of the reaction. The standard free energy decides the spontaneity of the reaction.
