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 `(A)` and `(R )` are correct, and `(R )` is the correct explnation of `(A)`.
B. If both `(A)` and `(R )` are correct, but `(R )` is noth the correct explanation of `(A)`.
C. If `(A)` is correct, but `(R )` is incorrect.
D. If `(A)` is incorrect, but `(R )` is correct.

Answer

B

Explanation

`A+B rarr X**rarr 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.
