Chapter 17, Problem 37QRT

(a)

Interpretation Introduction

Interpretation:

The value of ${\Delta }_{\text{r}}G°$ for the given reaction has to be calculated.

Concept Introduction:

Cell potential can be used to tell the possibility of the reaction to occur. The reactions having a positive value of $E_{\text{cell}}$ will proceed in the forward direction whereas those having negative value of $E_{\text{cell}}$ proceed in backward direction.

(b)

Interpretation Introduction

Interpretation:

If the equation is written with all coefficients doubled, then the value of ${\Delta }_{\text{r}}G°$ and $E_{}^{\text{ο}}$ for the new equation has to be calculated,

Concept Introduction:

Refer to part (a).
