Question

For a multistep reaction the observed order of
the reaction is generally determined by the
1. stoichiometric coefficients of the net reaction.
2. ratio of reactant and product concentrations.
3. slowest reaction of the sequence.
4. time at which the concentrations of all
species are measured.
5. activation energy.

Answer 1

Answer: 3 slowest reaction of the squence

Explanation:

Answer 2

The order of reaction is obtained from the slowest step in the reaction.

An elementary reaction refers to any reaction that takes place in one reactive encounter. On the other hand, a multistep reaction occurs in several steps and involves multiple reactive encounters.

The rate determining step in a multistep reaction is the slowest step in the reaction sequence. The order of reaction is obtained from this slowest step in the reaction.
