Question
This image is a graph depicting the free energy changes during a chemical reaction. The x-axis represents the "Progress of the Reaction," while the y-axis denotes "Free Energy." 

The reaction proceeds from the reactants (A + B) to the products (C + D), passing through a transition state.

- **Line a**: Represents the difference in free energy from the reactants to the top of the energy barrier (the transition state). This is the activation energy required for the forward reaction.

- **Line b**: Indicates the change in free energy from the reactants to the point just before the transition state. 

- **Line c**: Shows the difference in energy between the transition state and the products. 

- **Line d**: Represents the change in free energy from the transition state to the products, essentially the energy released.

- **Line e**: The overall change in free energy (ΔG) of the reaction from A + B to C + D. This line represents the energy difference between the reactants and the products, indicating the spontaneity of the reaction.

**Question**: Which of the following represents the ΔG of the reaction in the above figure? 

The correct answer is **Line e**.
