Unformatted text preview: We cannot see nor isolate intermediates in a chemical reaction- Reactions will have intermediates which are necessary for the conversion of reactants to products. The slowest step in a process determines the overall reaction rate . Enzymes do not alter the thermodynamics (like ΔH and ΔS values) of the reaction equilibria, but do affect the kinetics of the reaction.- Enzymes affect reaction rates, not reaction equilibria . Reaction intermediates will not appear as products of the overall reaction. Enzymes are not used up in a reaction, and their presence in the product signifies completion of a reaction The greater the concentration of the reactants, the faster the reaction rate; the higher the temperature of the reaction mixture, the faster the reaction rate; the lower the activation energy, the faster the reaction rate. Catalysts remain unchanged at the end of a reaction. The rate law can only be determined experimentally- Cannot be determined simply by looking at the balanced equation.Cannot be determined simply by looking at the balanced equation....
