In order for a reaction to proceed spontaneously from left to right as written,
A)ATP must be involved in the reaction.
B)a common intermediate must be formed.
C)the overall free-energy change must be negative.
D)a phosphate group must be transferred.
E)All of the above.

Question

Quizplus · Accepted Answer

According to the second law of thermodynamics, a reaction is spontaneous when the overall free-energy change is negative (ΔG < 0). This means that the products of the reaction have lower free energy than the reactants. Therefore, the statement that the overall free-energy change must be negative is the only true statement. Choices A, B, and D are not universally true for all reactions that proceed spontaneously.
