10PRACTICE PROBLEM
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
ΔG°f, SO3(g) = −371.1 kJ/mol
What is the equilibrium pressure of SO2 in the system at 298 K when PSO2 = PO2 and PSO2 = 45 torr?
