Question

Consider a diagram showing the effect of temperature on the spontaneity of reactions, as summarized in Table 5.4. Which of the following combinations of $ \Delta_r H^0 $, $ \Delta_r S^0 $, and $ \Delta_r G^0 $ represents a reaction that is spontaneous at high temperature but nonspontaneous at low temperature?

Accepted Answer

$ \Delta_r H^0 > 0 $, $ \Delta_r S^0 > 0 $, $ \Delta_r G^0 < 0 $ at high T

Answer

$ \Delta_r H^0 < 0 $, $ \Delta_r S^0 < 0 $, $ \Delta_r G^0 < 0 $ at low T

Answer

$ \Delta_r H^0 < 0 $, $ \Delta_r S^0 > 0 $, $ \Delta_r G^0 < 0 $ at all T

Answer

$ \Delta_r H^0 > 0 $, $ \Delta_r S^0 < 0 $, $ \Delta_r G^0 > 0 $ at all T
