Question

What is the Δ_rG° for the following reaction (in kJ mol^-1)?

2 NO_{2 (g)} ⇌N₂O_{4 (g)}

To solve, use Appendix II in your textbook (containing standard Gibbs energies of formation) and use the method of Gibbs energy of formation.

Answer 1

C(g) + dD(g) For the reaction, aA(g) + bB(g) = (AG)reaction = (EAG)product – (EAG)reactant (AG) reaction = Gc + GD - GA - GB
