Question 8 2 pts Which of the statements are TRUE? Select all that are true. The AG of a reaction is negative when Q-K Under standard state conditions, Q is always 1. Under standard state conditions, Q = K. At equilibrium, AG-AG. At equilibrium, AG=0. AG is a measure of how far the system is from standard conditions. The sign on AG indicates the direction a system will proceed to reach equilibrium from any initial conditions. None of the statements...
