In the free energy diagram below, molecule A (with energy x) is converted to molecule B (with energy z). The peak of the energy curve has energy y. The values x, y, and z represent some numerical value of free energy.

[Graph Description]
- The graph plots Free Energy on the vertical axis and Reaction Pathway on the horizontal axis.
- Molecule A starts at point x with a certain amount of free energy.
- The curve rises to a peak at point y, indicating the activation energy required for the reaction.
- The energy then decreases to point z, where molecule B is formed.

Which of the following represents:

A. Activation energy (Eₐ) of this reaction?
    [ Select ]

B. Gibbs Free Energy Change (ΔG)?
    [ Select ]

C. Is ΔG for this reaction positive or negative?
    [ Select ]

D. Is this reaction exergonic or endergonic?
    [ Select ]

E. Is this a spontaneous or nonspontaneous reaction?
    [ Select ]
