Question

The reaction

2 NO(g) ⇆ N₂O₄(g)

occurs at 25^oC under standard state conditions with ΔG^o = 13.1 kJ/mol. What is the free energy change (in J/mol) when the NO partial pressure is 0.649 Atm and the N₂O₄ partial pressure is 0.0015 Atm?

Expert Solution

Given

The equilibrium reaction given in the question is -

2 NO (g) $⇌$ N₂O₄(g)

Standard Gibbs free energy, ΔG^o = 13.1 kJ/mol = 13100 J/mol

The partial pressure of NO = 0.649 atm

The partial pressure of N₂O₄ = 0.0015 atm

Temperature, T = 25^oC = 298 K

The Gibbs free energy

The standard Gibbs free energy is given as-

$∆ G ° = - R T \ln K$

The Gibbs free energy at non-standard conditions is given as-

$∆ G = ∆ G ° + R T \ln K$
