For a gaseous reaction, standard conditions are 298 K and a partial pressure of 1 atm for all species. For the reaction C₂H(g) + H₂(g) = 2 CH₂(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 PC₂H₂ = 0.100 atm, PH₂ = 0.200 atm, and PCH, = 0.600 atm? AG= 7.0885 Incorrect kJ/mol

Question
For a gaseous reaction, standard conditions are 298 K and a partial pressure of 1 atm for all species.
For the reaction
C₂H(g) + H₂(g) = 2 CH₂(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
= 0.600 atm?
pressures are PC₂H₂ 0.100 atm, PH₂ = 0.200 atm, and PCH4
AG =
7.0885
Incorrect
=
kJ/mol
