1 Chap 4 3 Rxn factors 1. Mechanism- step by step description of the movement of e’ and atoms. 2. Thermodynamics- energy changes 3. Kinetics- reaction rates Gibbs free energy Δ G = Δ H - T Δ S Δ G = (+) non-spon., (-) spon. Δ H = enthalpy heat energy, (-) exothermic, (+) endothermic Δ S = entropy (disorder), (+) more disorder, (-) less disorder T = related to kinetic energy favorable – (-) enthalpy, (+) entropy, high T Activation energy- minimum kinetic energy needed to overcome repulsion. K = Ae -Ea/RT rate = k[A] x [B] y A = constant K = rate constant Catalyst- lowers activation energy. Transition state- highest energy state in a molecular collision. Intermediate- isolatable. Reactive Intermediates- Ex. For carbon. reactants products activation energy Δ H of reaction transition state Δ H
