(a)

Interpretation Introduction

Interpretation:

The value of $\Delta G_R°,\Delta S_R°$ and $\Delta H_R°$ for ${\text{FeO}}_{\left(\text{s}\right)}\text{+}{\text{CO}}_{\left(\text{g}\right)}\stackrel{}{\rightleftarrows }{\text{Fe}}_{\left(\text{s}\right)}{\text{+CO}}_{\text{2}\left(\text{g}\right)}$ reaction at 700^oC should be calculated.

Concept Introduction:

Gibbs free energy is that energy which is used to do some work.

  $\begin{array}{c}\text{ΔG}\text{=}{\text{ΔG}}^{{}^{\text{0}}}\text{+}\text{RTln}\text{Q}\\ \text{at}\text{equilibrium}\\ \left({\text{Q}}_{\text{p}}\text{=}{\text{K}}_{\text{p}}\right)\\ \text{ΔG}\text{=0}\\ {\text{0=ΔG}}^{{}^{\text{0}}}\text{+}\text{RTln}{\text{K}}_{\text{p}}\end{array}$

(b)
