Chapter 5, Problem 5A.4E

Interpretation Introduction

Interpretation:

The biological standard Gibbs energy change of given reaction has to be calculated.

Concept Introduction:

Gibbs free energy can be used to calculate the maximum amount of reversible work performed by a thermodynamic system at constant temperature and pressure. Symbol = G, Unit = Joule (J)/mol.

$\Delta G=\Delta G^0+RT\ln Q\boxed{\begin{array}{l}here,\Delta G=Gibbsfreeenergy\\ \Delta G^0=ChangeinGibbsfreeenergy\\ R=Gas\text{constant}\\ \text{T}\text{=}\text{Temperature}\end{array}}$

Concentration of the solution can also expressed by mole fraction. Mole fraction is equal to moles of the component divided by total moles of the mixture.

$\text{Mole fraction =}\frac{\text{moles of a component}}{\text{total moles}}$
