Which is NOT a necessary requirement for a proper reaction mechanism?
A) The rate-determining step must be the first step
B) An elementary step may be unimolecular
C) The sum of elementary steps must equal the net balanced chemical equation
D) An intermediate must be produced in an early step and consumed in a later step
Homework Answers
A) The rate-determining step must be the first step - is not a necessary requirement for a proper reaction mechanism.
this can be explained by the rate of a different reaction. The slowest reaction step where a higher amount of energy is required is the rate-determining step. This measure may be Step-1 or step-2 or any other step not necessary to be step-1.
There are many reactions where the first step is the reversible reaction and second or third step are the slowest steps so this slowest step must be the rate-determining step.

To understand how elementary steps make up a mechanism and how the rate law for an elementary step can be determined. Very often, a reaction does not tell us the whole story. For instance, the reaction NO2(g)+CO(g)→NO(g)+CO2(g)NO2(g)+CO(g)→NO(g)+CO2(g) does not involve a collision between an NO2NO2 molecule and a COCO molecule. Based on experimental data at moderate temperatures, this reaction is thought to occur in the following two steps: NO2(g)+NO2(g)→NO3(g)+NO(g)NO2(g)+NO2(g)→NO3(g)+NO(g) NO3(g)+CO(g)→CO2(g)+NO2(g)NO3(g)+CO(g)→CO2(g)+NO2(g) Each individual step is called an elementary step. Together, these...
