± Gibbs Free Energy: Temperature Dependence Gibbs free energy (G) is a measure of the spontaneity of a chemical reaction. It is the chemical potential for a reaction, and is minimized at equilibrium. It is defined as G=H−TS where H is enthalpy, T is temperature, and S is entropy.

� Gibbs Free Energy: Equilibrium Constant Nitric oxide, NO, also known as nitrogen monoxide, is one of the primary contributors to air pollution, acid rain, and the depletion of the ozone layer. The reaction of oxygen and nitrogen to form nitric oxide in an automobile engine is N2(g)+O2(g)?2NO(g) The spontaneity of a reaction can be determined from the free energy change for the reaction, ?G?. A reaction is spontaneous when the free energy change is less than zero. A reaction...

1. Explain in words what happens when a salt (i.e., NaCl) dissolves in water in terms of interactions that are lost and interactions that are gained. Explain for methanol (CH3OH) in water. Explain for a wax (hydrocarbon – all C’s and H’s) in water. 2. If DH1 is the enthalpy change for separating particles of solute, DH2 is the enthalpy change for separating particles of solvent, and DH3 is the enthalpy change for the formation of interaction between solute and...
