Calculate the equilibrium constant for the following reaction at 25o C, given that change in standard Gibbs free energy (f) of O3 (g) is 163.4 kJ/mol.
2O3(g) -> 3O2(g)
Expert Answer
Given:
The free energy change is 163.4 kJ/mol.
Temperature = 250C = 25 + 273 K = 298 K.
The relation between free energy change and equilibrium constant is:
Where
R = gas constant =8.314 J /mol K.
T = temperature.
K = equilibrium constant.
ln K = log of K (base e).
