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...

AG RT In = RT In Q- RT In K When the system is at equilibrium...
AG RT In = RT In Q- RT In K When the system is at equilibrium Q=1 and thus lIn 1-0, so then we can use this equation AG =-RT In K to find the temperature (solve for T). Remember T will be in K. Once we have the temperature we then use the following equation to calculate AG AG= AG+ RT In Q These molecular scenes represent three mixtures in which A2 (black) and B2 (green) are forming AB....
