Chapter 6, Problem 6C.2P

Interpretation Introduction

Interpretation: The value of ${\Delta }_{\text{f}}G°$ for ${\text{H}}_{\text{2}}\text{O}\left(\text{l}\right)$ has to be calculated.

Concept introduction: The standard reaction Gibbs energy can be calculated using the standard potential of the cell.  The expression to calculate the standard reaction Gibbs energy is given by the formula.

    ${\Delta }_{\text{r}}G°=-vF{E}_{\text{cell}}^{\text{ο}}$

Where,

• ${\Delta }_{\text{r}}G°$ is the standard reaction Gibbs energy.
• $v$ is the number of electrons.
• $F$ is the Faraday’s constant.
• $E_{\text{cell}}^{\text{ο}}$ is the standard potential of the cell.
