ΔG° = 23192 J/mol
Explanation:
For the reaction:
2 HI (g) ⇌ H₂(g) + I₂(g)
It is possible to find Kp thus:
Kp = P(H₂) P(I₂) / P(HI)²
Replacing:
Kp = 4,79x10⁻⁴ × 4,79x10⁻⁴ / (3,53x10⁻³)²
Kp = 0,0184
As moles of products (2) are the same moles of reactants, Kp = K
It is possible to find ΔG° from K, thus:
ΔG° = -RT ln K
where R is 8,314472J/molK, temperature in kelvin is 425 + 273,15 = 698,15K and K is 0,0184
Replacing:
ΔG° = -8,314472J/molK × 698,15K ln 0,0184
ΔG° = 23192 J/mol
I hope it helps!
