Gibbs Energy The tendency for a reaction to occur depends on both and H S. If is ________________ and is _______________ for a reaction, the reaction will likely H S If is positive and is negative for a reaction, the reaction will H S not How can you predict what will happen if and are both positive or both negative? H S ________________________ is the energy in a system that is available for work represented by the symbol G. = G H TS – Another name for Gibbs energy is ____________________. Gibbs Energy Determines Spontaneity!!! A reaction is one that does occur or is likely to occur ________________________ without continuous outside assistance, such as input of energy. A reaction is spontaneous if the Gibbs energy change is negative. A ________________________ reaction will never occur without assistance. If a reaction has a greater than 0, the reaction is nonspontaneous. G If a reaction has a of exactly zero, the reaction G is at equilibrium. Entropy and Enthalpy determine Gibbs energy Reactions that have __________________________ values often release energy and G increase disorder.
