I just took a test today, and I want to see if I got the right answer. I sort of guessed. Here's the question: Which statement is correct? a) When Q<K, then ∆G=1 b) When Q<K, then ∆G=-∆S c) When Q=K, then ∆G=0 d) When Q>K, then ∆G=1 e) When Q>K, then ∆G=-RT I put C, because when Q=K, the system is at equilibrium. I don't really know what ∆G is though other than that it's Gibb's Free Energy. Please explain your answer. Thanks so much!!!!!!
