Document Summary
All chemical reactions are governed by the laws of thermodynamics: first law, energy can neither be created nor destroyed, only converted from one form to another. If the reactants have greater energy than the products, then energy must be released. Types of chemical reactions: spontaneous, release energy, can occur without outside help (energy, spontaneous (- g, exergonic, non-spontaneous, requires free energy, can occur only with outside help (energy, non spontaneous (+ g, endergonic, chart goes up because energy is required. In all non-spontaneous reactions: g+ (increases) endergonic therefore the question of interest to us: is g (+ or -) ?? (enthalpy increases, entropy decreases: as enthalpy decreases, entropy increases (spontaneous) Changes in free energy (g: energy that is free and available to do work, amount of energy released or required when/for reactions/processes to occur. G = change in free energy (if spontaneous, it is negative)
