Textbook Problem

You remember that ∆G° is related to RT ln(K) but cannot remember if it’s RT ln(K) or − RT ln(K). Realizing what ∆G° and K mean, how can you figure out the correct sign?

Interpretation Introduction

Interpretation: The correct expression for ΔG° is to be stated.

Concept introduction: The equilibrium state is attained in a chemical reaction when the free energy corresponds to the minimum value that is available to a given system.

To determine: The correct expression for ΔG° .

Explanation

Explanation

Given

The ΔG° is related to RTln(K) .

The constant K is the equilibrium constant.

The equilibrium state is attained in a chemical reaction when the free energy corresponds to the minimum value that is available to a given system.

Therefore, the correct sign to be used is the negative sign
