Energy can neither be created nor destroyed only converted from one form to another. Second law: when converting energy from one form to another the amount of useful energy decreases. Spontaneous reactions: releases free energy (exergonic, reactants have more energy than the products. Stable = high activation energy: a molecule or atom is stable when its activation energy is high. If the change is negative, the reaction is spontaneous. If the change is positive, the reaction is non-spontaneous: g = h t( s, g = free energy, h = enthalpy. The amount of energy that could be released in heat. Increases when heat is taken up in a reaction: decreases when heat is released in a reaction, = the change in (a variable); delta. T = temperature (k: all positive values.
