4. A. B. C. D. E. 5. A. Which one of the following statements is correct? A catalyst that is present in the same phase as the reacting molecules is a heterogeneous catalyst. Elementary steps involving the simultaneous collision of two molecules are bimolecular. Absorption refers to the binding of molecules to a surface. Because the fast step limits the overall reaction rate, it is called the rate- determining step. A balanced chemical reaction equation details the individual steps that occur in the course of a reaction. A reaction NO₂(g) + CO(g) → NO(g) + CO₂(g) obeys the following rate law: Rate = K[NO₂]². What are the units for the rate constant? M-¹ S-1
