Document Summary
Free energy change ( g) is a process that determines whether that process will require energy or release energy. A system is any part of the universe that we choose for study, and the system may be isolated, and thus unable to exchange energy and matter with its surroundings. The system could also be closed, so it is able to exchange energy but not matter, or the system can be open, so that both energy and matter can pass between the system and surroundings. It states that in a closed system, the energy is conserved. The change in enthalpy for any system is defined as the difference in the enthalpy between the final and initial states of the system: A reversible process (melting ice) is always at a near state of equilibrium. An irreversible process (burning paper) happens when systems are set up far from an equilibrium state, and then they drive toward a state of equilibrium.
