The Gibbs free energy of activation is:
A) the difference between the substrate and the transition state.
B) the difference between the substrate and the product.
C) the difference between the product and the transition state.
D) All of the above.
E) None of the above.

Question

Quizplus · Accepted Answer

The Gibbs free energy of activation is defined as the difference in energy between the reactants (substrate) and the transition state. This energy difference is important because it represents the energy required to reach the transition state, which is the point of highest energy in a chemical reaction. The difference between substrate and product (option B) is the standard Gibbs free energy change, while the difference between product and transition state (option C) is not a relevant or defined concept.
