Match each term with its definition. 1) reaction coordinate a) represents the additional free energy that molecules must have to attain the transition state 2) δg° b) a generalized measure of the progress of the reaction through intermediate states 3) δg°‡ c) free energy of the reaction

Reaction coordinate ⇒ a generalized measure of the progress of the reaction through intermediate states.

ΔG° ⇒ free energy of the reaction.

ΔG°‡ ⇒ represents the additional free energy that molecules must have to attain the transition state.

Explanation:

Reaction coordinate is a diagrammatic chart expressing a generalized measure of the progress of the reaction through intermediate states.

The free energy, G , of a chemical system is the free energy which is available for doing work. It is the driving force that brings about a chemical change.

In the Arrhenius equation, the term activation energy (Ea) is used to describe the energy required to reach the transition state. A superficially similar mathematical relationship, the Eyring equation, is used to describe the rate of a reaction.THUS, Instead of also using Ea, the Eyring equation uses the concept of Gibbs energy and the symbol ΔG‡ to denote the Gibbs energy of activation to achieve the transition state.
