Question “Calculate ΔS∘rxn for the following balanced chemical equation: 2H2S(g) + 3O2(g) → 2H2O(g) + 2SO2(g) Substance and stat…”
Calculate ΔS∘rxn for the following balanced chemical equation:
2H2S(g) + 3O2(g) → 2H2O(g) + 2SO2(g)
Substance and state S∘[J/(K⋅mol)]
H2O(g) 188.8
O2(g) 205
H2S(g) 205.7
SO2(g) 248.1
Answer
Delta S_rxn degree = S_products degree – S_reactant degree = {[2 s_H_2 O degree + 2 S_SO_2 degree] – [2 S_H_2 S degree + 3 S_O_2 degree]} {[2(188.8) + 2(248.1)] – [2(205.7) + 3 (205)]} {[377.6 + 496.2] – [411.4 + 615]} = -152.6 J/k mol
Conclusion
Above is the solution for “Calculate ΔS∘rxn for the following balanced chemical equation: 2H2S(g) + 3O2(g) → 2H2O(g) + 2SO2(g) Substance and stat…“. We hope that you find a good answer and gain the knowledge about this topic of science.
