Question

Ina complex reaction the order of reaction is ________ molecular a) eqval ?

Answer 1

Answer:

In a complex reaction the order of the reaction is not equal to molecularity

Explanation:

$\blacksquare$ Order :

$\implies$ It is an experimental value

$\implies$ It tells us about the relationship between concentration and rate of the reaction

$\blacksquare$ Molecularity

$\implies$ It is a theoretical value

$\implies$ It is defined as the number of molecules that collide simultaneously together in a chemical reaction

$\blacksquare$ For a simple or elementary reaction,

$\boxed{ORDER = MOLECULARITY}$

$\blacksquare$ We know that, a complex reaction is a combination or compilation of 2 or more elementary reactions

$\blacksquare$ Each of these simple reactions have different order and molecularity

$\blacksquare$ Hence, for a complex reaction

$\boxed{ORDER \neq MOLECULARITY }$
