The reaction rates of many spontaneous reactions are actually very slow.Which of these statements is the best explanation for this observation? A)(K_p for the reaction is less than one.) B)The activation energy of the reaction is large. C)($\Delta$G° for the reaction is positive.) D)Such reactions are endothermic. E)The entropy change is negative.

Question

Quizplus · Accepted Answer

The slow reaction rate suggests that the reactants require a high amount of energy to reach the transition state and proceed to form products. This indicates that the activation energy of the reaction is large. The other choices do not provide a satisfying explanation for the slow rate of a spontaneous reaction.
