s by lowering the Ea: • Catalysts speed forward and reverse reactions • However, most reactions favour the side that has the lowest potential energy (most stable) • Catalysts are heterogenous or homogenous • They provide a substrate (p. 768) for a reaction or they can bond temporarily to a molecule, increasing the odds of a favourable meeting Fraction of molecules Kiic energy potential energy Path of reaction Transition state lab: purpose Purpose: 1) to visualize an activated plex, 2) to observe the influence of a catalyst We will be examining the following reaction: NaKC4H4O6(aq) + H2O2(aq) CO2(g) + … Procedure: 1. Turn hot plates immediately to medium heat 2. Get a 10 mL graduated cylinder, a 100 mL beaker, a test tube, and a rubber stopper. 3. Weigh g NaKC4H4O6. Add to beaker along with 10 mL distilled H2O. Swirl to dissolve. 4. Add mL of 10% H2O2 to beaker. Heat. 5. Get 5 mL of CoCl2 but don’t add it。阅读剩余 0%
