Question

Why moleclarity is applecable for elementry reaction and order of the reaction is applecable for elementry reaction?

Answer 1

Answer:

a complex reaction occurs through numbered of elementary reaction ..

the number of atoms in reactions mat be different ..

Answer 2

Answer:

molecularity is number of colliding molecular entities that are involved in a single reaction step. Since complex reaction is broken into simpler elementary reaction therefore, the molecularity can be written for only elementary reaction not for complex reactions.
