Question

Calculate the Gibbs free energy for the conversion of oxygen to Ozone at room temperature if KP is given as 2.47 x 10-29.

• A. 163 kJ/mol
• B. 163 J/mol
• C. 163 kJ
• D. 163 k/mol

Answer 1

Answer:

A. 163 kJ/mol

The chemical equation for the conversion of oxygen to Ozone is 3/2O2 → O3. We have the equation, ΔG = – 2.303 RT log Kp. So by substituting we get ΔG = – 2.303 x 8.314 J/K-mol x 293K x 2.47 x 10-29 = 163000 J/mol = 163 kJ/mol.
