Calculate the DELTA H(rxn), DELTA S(rxn), DELTA S(universe), DELTA G(rxn). For each system below indicate whether DELTA S and DELTA H are positive or negative. Then indicate if the reaction is entropy driven, enthalpy driven or neither.
C3H8(g) + 2O2(g) => 3CO2(g) + 4H2O(g)
You need to look in your text for a set of thermodynamic tables and apply the following:
delta H(rxn) = delta H products - delta H reactants.
delta S(rxn) = delta S products - delta H reactants.
Then delta G = delta H - T*delta S.
