Quizplus · Accepted Answer

There are two transition states present in the energy diagram, one between the reactants and the intermediate, and another between the intermediate and the products. Choice A is incorrect because there must be at least one transition state present in any chemical reaction. Choice B is incorrect because there is more than one transition state present. Choice D is incorrect because there are only two transition states present, not three.
