Gibbs free energy equation variables

WebThe temperature is that of both the system and surroundings. The whole point of "free energies" is that you must imagine: The system to be in thermodynamic equilibrium at all times so that, a fortiori this means that the system and environment must be at the same temperature, and, The system's thermodynamic macrostate to be "cycled", i.e., … WebQuestion: *Solve for G, H and S by using/manipulating and solving for any of these variables in the equation related to Gibbs free energy, and predict based on that solution if a reaction is spontaneous or not. * Explain how ATP is used as a source of energy to drive endergonic reactions.
