If ΔG is negative, the reaction is always spontaneous. If ΔG is positive, the reaction is non-spontaneous and will require a sustained input of energy for it occur. If ΔG is zero, the reaction is at equilibrium and no work can be done.
a the answerFor an endergonic reaction, the statement ΔG is positive is the true statement. So the first option in the given question is the correct option.
