Difference between order and molecularity reaction

Answer~

$\bigstar \pink {Order \: of \: the \: reaction }$

• The sum of powers the concentration of the reactant in the rate law expression is called the order of reaction.
• Order can be 0, 1, 2, 3 and even a fraction.
• It applicable to both elementary and complex reaction.

$\bigstar \pink{Molecularity \: of \: the \: reaction }$

• The number of reacting species taking part in an elementary reaction which colloid simultaneously in order to bring about the chemical reaction is called molecularity.
• Molecularity can't be zero or a non integer.
• It is applicable to only elementary reaction.
