How do you determine rate law from rate-determining step?
A reaction intermediate is a chemical species that is formed in one elementary step and consumed in a subsequent step. The slowest step in a reaction mechanism is known as the rate-determining step. The rate-determining step limits the overall rate and therefore determines the rate law for the overall reaction.
What is the correct expression for the rate law for step 1 with rate constant k_1?
A The rate law for step 1 is rate = k1[NO2]2; for step 2, it is rate = k2[N2O4][CO]. B If step 1 is slow (and therefore the rate-determining step), then the overall rate law for the reaction will be the same: rate = k1[NO2]2. This is the same as the experimentally determined rate law.

|---|---|
| Gives the rate of a particular reaction. | Gives the favouring direction in which reaction will proceed. |
Why does the rate of any reaction January decreases during the course of the reaction?
Answer : The rate of a reaction generally decreases with the course of the reaction as the concentration of reactant decreases as soon as the formation of product starts. So during the course of a reaction the concentration of reactant becomes less than that present initially.
How do you calculate rate of reaction from a graph?

Can rate law be determined from reaction stoichiometry?
Rate laws are determined experimentally and cannot be predicted by reaction stoichiometry.
