# Question: Using data from Appendix 4 calculate G for the reaction 2H2S g

Using data from Appendix 4, calculate ΔG for the reaction

2H2S(g) + SO2(g) ⇌ 3S(s) + 2H2O(g)

for the following conditions at 25oC:

PH2S = 1.0 × 10–4 atm

PSO2 = 1.0 × 10-2 atm

PH2O = 3.0 × 10-2 atm

2H2S(g) + SO2(g) ⇌ 3S(s) + 2H2O(g)

for the following conditions at 25oC:

PH2S = 1.0 × 10–4 atm

PSO2 = 1.0 × 10-2 atm

PH2O = 3.0 × 10-2 atm
