Which statement best describes the relationship between the heat of reaction and reaction rate?
A) There is no readily predictable relationship between ΔH and reaction rate.
B) Exothermic reactions are always slow.
C) Endothermic reactions are always slow.
D) The heat of reaction is always larger than reaction rate.
E) The relationship depends on whether the reaction is endothermic or exothermic.

Question

Quizplus · Accepted Answer

The relationship between the heat of reaction (ΔH) and the reaction rate is not directly predictable because the reaction rate is primarily determined by the activation energy and the concentration of reactants, not by whether the reaction is exothermic or endothermic.
