Question

distinguish between order and molecularity of reaction​

Answer 1

Answer:

Molecularity

• It represents the number of the reactant molecules taking part in the elementary reaction
• It is theoretical property and indicates the number of reactant molecules involved in each act leading to the reaction.
• It is always an integer and can never be fraction or zero.
• It is the property of only elementary reaction and has no meaning for complex reactions

Order

• It represents the sum of the exponents to which the concentration term in the rate law are raised.
• It is an experimental property and indicates the dependence of observed reaction rate on the concentration of the reactants.
• it may be an integer, fraction or zero
• it is property of both elementary and complex reactions.
