Chapter 21, Problem 21.65QP

Interpretation Introduction

Interpretation:

The wrong with the given procedures for obtaining magnesium has to be derived.

Concept introduction:

• The problem occurs in the procedure will be found by using the equilibrium constant.
• The relationship between $\Delta G^{\circ }$ and equilibrium constant is

$\Delta G^{\circ }=-RT\ln K_p$

• To calculate $\Delta G^{\circ }$ values for the given reaction we have to use the following formula

$\Delta G_{\text{rxn}}{}^{\circ }=\Delta G_{\text{f}}{}^{\circ }\left(products\right)-\Delta G_{\text{f}}{}^{\circ }\left(substrates\right)$
