Calculate the G0rxnat350C using the following information: 2H2S(g)+ 3O2(g) 2SO2(g) +2H2O(g) Hof(kJ/mol) -20.0 0 -296.8 -241.8 S0(J/mol) 205.8 205.2 248.2 188.8 Calculate the G0rxnat350C using the following information: 2H2S(g)+ 3O2(g) 2SO2(g) +2H2O(g) Hof(kJ/mol) -20.0 0 -296.8 -241.8 S0(J/mol) 205.8 205.2 248.2 188.8 Hof(kJ/mol) -20.0 0 -296.8 -241.8 S0(J/mol) 205.8 205.2 248.2 188.8Explanation / Answer
Formula: G0rxn = Ho - TS0 Ho = Ho products - Ho reactants S0 = S0 products - S0 reactants Ho =(2 moles * -296.8 kJ / mol + 2 moles * -241.8 kJ / mol) - ( 2 moles * -20.0 kJ / mol + 3 moles * 0 kJ / mol ) = (-593.6 kJ -483.6 kJ ) - ( -40 kJ ) = -1037.2 kJ S0 = (2 moles * 248.2J /K mol +2 moles * 188.8 J /K. mol ) - ( 2 moles * 205.8 J /K mol + 3moles * 205.2 J /K. mol ) =( 496.4 J/ K + 377.6 J / K ) - ( 411.6 J / K + 615.6 J / K) = -153.2 J / K T S0 = 308 K ( - 153.2 J /K) =-47.2 kJ G0rxn =-1037.2 kJ - ( -47.2 kJ) = -990.0 kJRelated Questions
