5)
a) At what temperatures is a reaction spontaneous if it has a deltaH0rxn = -88 kJ/mol and a deltaS0rxn = -247 J/K mol.
b) At what temperatures is a reaction spontaneous if it has a deltaH0rxn = -88 kJ/mol and a deltaS0rxn = +247 J/K mol.
c) At what temperatures is a reaction spontaneous if it has a deltaH0rxn = +88 kJ/mol and a deltaS0rxn = -247 J/K mol.
d) At what temperatures is a reaction spontaneous if it has a deltaH0rxn = +88 kJ/mol and a deltaS0rxn = +247 J/K mol.
e) Look at your answers for parts a)-d) above and describe how you can determine under which conditions a reaction is spontaneous or not based on the respective signs of deltaH0rxn and deltaS0rxn.
