Chemistry Question on Order of reaction

For a complex reaction, the order of reaction is equal to:

A

Sum of stoichiometric coefficients

B

Molecularity of the overall reaction

C

Order of the fastest step

D

Molecularity of the slowest step

Answer

Molecularity of the slowest step

Explanation

Solution

For a complex reaction, the overall order of the reaction is determined by the molecularity of the slowest step, also known as the rate-determining step.
