A catalyst is involved or not for the reaction C H 3 C O O C H 3 ( a q ) + H 2 O ( l ) → C H 3 C O O H ( a q ) + C H 3 O H ( a q ) has to be checked. Also if a catalyst is present, it has to be identified as homogeneous or heterogeneous. Concept Introduction: Catalysts are those substances with alter the rate of reaction without being consumed or produced during the reaction. In rate law catalyst may appear but it will not appear in the overall reaction equation. If the chemical involved the rate law is not reactant or product, then it involves catalysts. Homogeneous catalysts are those chemicals that are in same phase with reactant and heterogeneous catalysts are in different phase with reactant.
