Reaction intermediate $-$ Activated complex

(B) In the potential energy curve,the transition state (activated complex) lies at the maxima,whereas the reaction intermediate lies at the minima.Location $1$ corresponds to a local minimum,which represents a reaction intermediate.Location $2$ corresponds to a local maximum,which represents a transition state (activated complex).Therefore,the correct identification is: Location $1$ $-$ Reaction intermediate,Location $2$ $-$ Activated complex.
