Abstract:
Kinetics and mechanism of reactions between iron (II) isocyanide complexes [FeL5 (CN)] Br (1, L = -CNCH2Ph); trans- [FeL4 (CN)2] 2, L = -CNCH2Ph) and oxygen atom transfer agent (CH3)3NO have been investigated in dichloromethane by UV-visible and Infrared spectrophotometers at different temperatures. The results revealed that the reactions proceed with second order and the rate law is rate = k2 [isocyanide complex] x [(CH3)3NO]. delta S not equal to and delta H not equal to for the reaction between complex 1 and (CH3)3NO are -25.34 +/- 1.67 cal.(mol.K)-1 and 12.71 +/- 0.49 kcal.mol-1 respectively. However, there is no reaction between 2 and (CH3)3NO. The reaction mechanism was proposed and the factors affecting the reaction rate were also discussed.

Rate-Determining Steps
In a multistep reaction mechanism, one of the elementary steps progresses significantly slower than the others. This slowest step is called the rate-limiting step (or rate-determining step). A reaction cannot proceed faster than its slowest step, and hence, the rate-determining step limits the overall reaction rate.
The concept of rate-determining step can be understood from the analogy of a 4-lane freeway with a short-stretch of traffic-bottleneck caused due to...
