Question
A certain hypothetical substance "AB", in the gaseous state,
dissociating to produce species A (in the gaseous state) and species
B (also in the gaseous state) according to the following equation
(Consider that the system is in balance).
AB(9) 2 A(g) + Bg)
At 300 K and a total pressure of 1 atm, the degree of dissociation
(alpha=advance/number of moles hypothetical reagent) of AB(g) is
0.2. Calculate the standard free energy variation for this reaction in
Joules per mol.
