a. The
reaction is both enthalpically and entropically opposed. It is nonspontaneous
(endergonic) at all temperatures. |
2. |
− |
− |
b. The
reaction is enthalpically opposed (endothermic) but entropically favored. It
is spontaneous only at temperatures above T = ΔH/ΔS. |

c. The
reaction is enthalpically favored but entropically opposed. It is spontaneous
only at temperatures below T = ΔH/ΔS. |
4. |

− |
d. The
reaction is both enthalpically favored (exothermic) and entropically favored.
It is spontaneous (exergonic) at all temperatures. |
