Solved Example Problems: Gibbs free energy (G)

Gibbs free energy (G), standard free energy change (ΔG0) and equilibrium constant (Keq)

Problem: 7. 8


 

Problem: 7.9

 

Calculate ΔG0  for conversion of oxygen to ozone 3/2 O↔ O3(g) at 298 K, if Kp for this conversion is 2.47 u 10−29 in standard pressure units.

 

Solution:

 

ΔG0 = − 2.303 RT log Kp

Where

 

R = 8.314 JK−1mol−1

 

Kp = 2.47 x10−29

 

T = 298K

 

ΔG0=−2.303(8.314)(298)log(2.47u10−29)

 

ΔG0 = 16300 Jmol−1

 

ΔG0 = 16.3 KJ mol−1
