Chapter 22, Problem 34P
Interpretation Introduction

Interpretation:

The rate enhancement provided by the catalyst has to be calculated

Concept introduction:

  • Catalyst: Substance which helps in increasing the rate of a particular reaction without getting consumed in the reaction.
  • The rate enhanced by the catalyst can be calculated by,

The rate constant for the uncatalyzed reaction of two molecules of glycine ethyl ester to form glycylglycine ethyl ester is 0.6 M-1s-1. In the presence of Co2+, the rate constant is 1.5 x 106 M-1s-1. What rate enhancement does the catalyst provide?
The rate constant for the uncatalyzed reaction of two molecules of glycine ethyl ester to form glycylglycine ethyl ester is 0.6 M- 1s - 1. In the presence of Co2 +, the rate constant is 1.5 * 106 M- 1s - 1. What rate enhancement does the catalyst provide?
[Rh(PPh3)3Cl] is a precatalyst that can be activated by dissociation of a phosphine ligand to form an active catalyst, B, which is used in the hydrogenation of alkenes. The active catalyst can then undergo oxidative addition in the presence of H2 to form complex C. Propene coordinates to C to form complex D, which then undergoes a 1,2- insertion step to form E. Reductive elimination of propane from E regenerates the active catalyst B. Draw complexes B – E and hence provide a full catalytic cycle, including the activation step, for the hydrogenation of propene
