Question

Molecules must overcome a barrier called the activation energy if they are to react. The highest energy point reached during the progress of a reaction is called the ____.

a. transition state
b. Arrhenius state
c. half-life
d. elementary step
e. intermediate state

what is each state?

Answer 1

a. Transition state

What is each state? I do not know. But a state at the highest energy point, but with a little dip in the middle, is called an intermediate, or a metastable state. I depends on whether you're talking about organic reactions or radioactive isotopes.
