And molecularity is not even defined except for elementary reactions, so there is no question of molecularity for multi-step processes. – S R Maiti Jul 22, 2024 at 3:05 1 There is always one step that will be the slowest even if the difference is miniscule. By definition there can only be one slowest step.
Define order of reaction and molecularity of reaction ... - Sarthaks
WebDec 23, 2024 · Assertion: The order of reaction can be zero or fractional. Reason: The order of a reaction cannot be determined from a balanced chemical reaction. Ans 1. B. 2. Assertion: The order and molecularity of a reaction are always the same. Reason: Order is determined experimentally whereas molecularity by a balanced elementary reaction. WebFeb 22, 2024 · The key difference between order of reaction and molecularity is that the order of reaction gives the relationship between the concentration of a chemical species and the reaction it undergoes whereas molecularity expresses how many reactant molecules are involved in the reaction.

What is the difference between the order and molecularity of
WebMolecularity refers to the amount of distinct molecules involved in a reaction while order refers to the exponent to which the concentration terms are raised to obtain the rate of … The number of reacting particles (molecules, atoms, or ions) that collide simultaneously in a rate determining step to form a product is called molecularity of a reaction. In general, the molecularity of simple reactions is equal to the sum of the number of molecules of reactants involved in the balanced … See more The order of reaction is defined as “ the sum of the coefficients (or power ) of the reacting species that are involved in the rate equation for the reaction.” The … See more Let us consider a general reaction: aA + bB + cC → Product Let active moles of A, B and C be α, β and γ respectively. Then the rate of reaction may be given as: Rate = … See more WebJul 11, 2024 · Therefore, the molecularity of a reaction can be used to determine the reaction order for an elementary step. Otherwise, when using the rate law, the reaction … gpz owners club
