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)

  • Chemistry -

    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.
