According to the tranistion state theory, for the formation of on activation complex, one of the vibrational degree of freedom is converted into the tranistion degree of freedom.
Reason (R ): The energy of the activated complex is higher than the energy of the reactant molecules.

Options

A. If both assertion and reason are true and reason is the true explanation of the assertion.
B. If both assertion and reason ae true but reason is not the true explanation of the assertion.
C. If assertion is true, but reason is false.
D. If both assertion and reason are false.

Answer

A

Explanation

`A+B to X^(*)to" Products"`
The activated complex `X^(*)` has higher energy than reactants. It is a special molecule which decomposes such that one vibrational degree of freedom is converted into a translational degree of freedom along the reaction coordinate.
