State the role of activated complex in a reaction and state its relation with activation energy.

Explanation

Activated complex is the intermediate compound formed by reactants which is highly unstable and readily changes into product.Those reactants which possess activation energy and collide in proper orientation can form activated complex which caneasily from products.Lower the actvation energy ,more easily activated complex will be formed and faster will be the reaction. Activation energy of activated complex-energy of reactants.
