We can use the following equation to solve for ΔS˚rxn:
Note that we need to multiply each S˚ by the stoichiometric coefficient since S˚ is in J/mol • K.
The given balanced equation for the reaction is 2 NO(g)+O2(g)→2 NO2(g)
S° NO2(g) = 240.0 J/(K•mol)
S° O2(g) = 205.2 J/(K•mol)
S° NO(l) = 210.8 J/(K•mol)
Calculate ΔS∘rxn for the reaction 2NO(g)+O2(g)→2NO2(g)
