Order and molecularity
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 WebApr 30, 2024 · The molecularity of a reaction is the number of molecules reacting in an elementary step. Reactions can be unimolecular (one reacting molecule), bimolecular (two reacting molecules) or termolecular (three reacting molecules).

Order and molecularity
Did you know?
WebMolecularity can be determined by the sum of the number of reacting species present in the reaction’s slow step. 4. Order is applicable to an elementary as well as a complex reaction. Molecularity is applicable only to the elementary reactions. Since, the molecularity of the overall complex reaction has no significance, molecularity of only ...

WebJun 20, 2024 · Assertion : Order of the reaction can be zero or fractional. Reason : We cannot determine order from balanced chemical equation. Assertion : Order and molecularity are same. Reason : Order is determined experimentally and molecularity is the sum of the stoichiometric coefficient of rate determining elementary step. WebOrder of reaction Molecularity can be defined as the number of atoms or molecules that must simultaneously collide together for a reaction to occur. Depending upon the number of molecules involved in the reaction, reactions are classified in terms of molecularity as unimolecular, bimolecular, and termolecular.
