  1. 3. reaction-specific biological catalysts. They react with a substrate to form an unstable intermediate compound.
  2. 4. Hydrogenation of a C=C double bond
  3. 5. cracking of petroleum
  4. 6. This reaction occurs when the catalyst and the reactant are in the same phase i.e. when the catalyst and the reactants are dissolved in the same solution.
  5. 7. a catalyst for the decomposition of hydrogen peroxide into oxygen gas and water.
  6. 8. ammonia synthesis
  7. 9. catalytic action is a (chemical/physical) reaction between the catalyst and a reactant
  8. 10. The only difference between a catalyzed reaction and an uncatalyzed reaction is that this energy is different.

  1. 1. This reaction occurs when the catalyst and the reactant exist in two different phases i.e. a solid catalyst in the presence of a reactant in solution.
  2. 2. With solid catalysts the <> is strongly influenced by surface properties and electronic or crystal structures.
  3. 9. a chemical substance that affects the rate of a chemical reaction by altering the activation energy required for the reaction to proceed.
