Justify the following sentences by answering (T) for TRUE or (F) for FALSE. (1 mark each) AE is independent on the initial and final state of a system. The sum of entropy changes of the system and surroundings is always positive. The ratio of numerical values of partial pressures of the reaction participants is unitless. Q is small if products pressures are small, a large Q means a negative or good (favorable) contribution to the free energy For pure solids...
