Chapter 18, Problem 18.104SP

Interpretation Introduction

Interpretation:

Provide the equations that give the relation between $E^{\circ }$ , $\Delta G^{\circ }$ and $K$. Show that $\Delta G^{\circ }$ is negative and $K>1$ for a reaction that has a positive value of $\Delta E^{\circ }$.

Concept Introduced:

The relationship between $E^{\circ }$ , $\Delta G^{\circ }$ and $K$ is given using below equations:

$\Delta G^{\circ }=-RTlnK$

  $\Delta G^{\circ }=-nF{E}^{\circ }$

Where, $\Delta G^{\circ }$ = free energy change for the reaction
      $E^{\circ }$ = Standard cell potential
      $n$ = Number of electrons transferred
      $F$ = Faraday’s Constant
      $R$ = Gas Constant
      $T$ = Temperature
