We’re being asked to determine the ΔS° for the given reaction:
We can use the following equation to solve for ΔS˚rxn:
Note that we need to multiply each ΔS˚f by the stoichiometric coefficient since ΔS˚f is in kJ/mol.
Part B. Calculate ΔS°rxn for the balanced chemical equation: H2S(g)+2O2(g)→H2O(g)+SO3(g)
