Influence of Some substances, known as catalysts, have the ability to speed up chemical reactions without being consumed in the process. Catalysts operate in a variety of different ways. Some provide an alternate, faster pathway for a reaction by forming intermediate compounds with one or more of the reactants (homogeneous catalysis). Others provide surfaces on which the reactants adsorb and react more easily (heterogeneous catalysis). The catalytic exhaust converter of automobiles is an example of a heteroge- neous surface catalyst. Whatever mechanism is involved, catalysts are very useful and important because of their rate-enhancing abilities Catalysts on Reaction Rates Experiment 14: Determination of K(a) for Weak Acids Experiment 15: The Acidic 207 Hydrogens of Acids Experiment 16: The Use of Melting Points in the...
