Free energy change of a reaction
Consider the combustion reaction for propane below.
CH3CH2CH3(g)+5O2(g)-------->3 C02(g)+4H20(g)

a) Determine the delta G standard state at 298 K from the following standard state values at T= 298
S(CH3CH2CH3)=269.9 J/K mol
S(C02)= 213.7 J/K mol
S(H20)=188.8 J/K mol
S(02)=205.1 J/ K mol
delta H(CH3CH2CH3)=-103.9 kJ/mol
delta H(C02)=-393.5 kJ/mol
delta H(H20)=-241.8 kJ/mol

b) Determine the delta G standard state at 1000K. assume delta H is independent of temperature
