Question
For a gaseous reaction, standard conditions are 298 K and a partial pressure of 1 atm for all species.
For the reaction
C,H, (g) + H, (g) =2CH,(g)
the standard change in Gibbs free energy is AG°
-72.6 kJ/mol. What is AG for this reaction at 298 K when the partial
pressures are Pc,H6
0.250 atm, PH, = 0.150 atm, and PCHA = 0.750 atm?
AG =
2.057
kJ/mol
Incorrect
