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 O2 ↔ 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
