Kinetic data and their interpretation - Some examples of the interpretation of activation parameters

3 important questions on Kinetic data and their interpretation - Some examples of the interpretation of activation parameters

What does the magnitude of dH‡ indicate?

It is a measure for the amount of binding energy that is lost in the transition state relative to the ground state.

What is dS‡ a measure for?

dS‡ is a measure for the difference in order between the transition state and the ground state.

What is in general valid for dS‡?

- for monomolecular reactions dS‡ ≈ 0 J/mol.K

- for bimolecular reactions dS‡ << 0 J/mol.K
