Question

Calculate the ΔG°_rxn using the following information. 2 H₂S(g)+ 3 O₂(g)→ 2 SO₂(g)+ 2 H₂O(g)ΔG°_rxn= ? ΔG°_f (kJ/mol)-33.4 -300.1 -228.6

Quizplus · Accepted Answer

The ΔG°_rxn can be calculated using the formula ΔG°_rxn = ΣΔG°_f(products) - ΣΔG°_f(reactants). For the given reaction, the ΔG°_f values for the products (2 moles of SO2 and 2 moles of H2O) and the reactants (2 moles of H2S and 3 moles of O2) are plugged into this formula. Since the ΔG°_f for O2 is 0 (as it is an element in its standard state), the calculation simplifies to: ΔG°_rxn = [2(-300.1) + 2(-228.6)] - [2(-33.4) + 3(0)] = -1057.4 + 66.8 = -990.6 kJ.
