19. Chemical Thermodynamics / Gibbs Free Energy And Equilibrium / Problem 8
The reaction SO2 (g) + 1/2 O2 (g) ⇌ SO3 is involved in the production of acid rain. The standard free energy of each substance is given below.
- ΔG°f (SO2 (g)) = −300.1 kJ/mol
- ΔG°f (O2 (g)) = 0 kJ/mol
- ΔG°f (SO3 (g)) = −371.1 kJ/mol
What is the equilibrium pressure of SO2 in the system at 298 K when peq (SO2) = peq (O2), and peq (SO3) = 45 torr?
