Unformatted text preview: the reverse reaction. For an endothermic process the reverse reaction is faster than the forward reaction. These conclusions are consistent with the Arrhenius equation the larger the E a , the smaller the value of k , and the slower the reaction: Larger E a smaller k decreased rate 1 Molecular Structure and Rate The molecules must collide such that the reacting atoms make contact. A collision must have enough energy and a particular molecular orientation to be effective. Transition State Theory The Activated State CH 3 Br + OH CH 3 OH + Br Draw an energy diagram for this reaction depicting the transition state (activated complex). Transition state theory suggest that every reaction (and every step in an overall reaction) goes through its own transition state. 2...
