E) None of the statements is true.

Question

Quizplus · Accepted Answer

The actual free-energy change for a reaction indeed varies depending on the standard free energy (a fixed value under standard conditions) and the concentrations of reactants and products. This is because the actual conditions (e.g., concentrations) can differ from standard conditions, affecting the free-energy change.
