Order and molecularity
WebOct 4, 2024 · Many reactions have the order of reaction different from the molecularity of the reaction. This case is mainly when one reactant is present in significant excess. Examples are Hydrolysis of ethyl acetate and inversion of cane sugar in an aqueous solution. Above reaction, the molecularity of each reaction is two, and the order of a reaction is one. WebMolecularity of a Reaction: The number of reacting species (atoms, ions or molecules) taking part 40 in an elementary reaction, which must collide simultaneously in order to bring about a chemical reaction is calledmolecularity of a reaction.

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. 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.
It is important to distinguish molecularity from order of reaction. The order of reaction is an empirical quantity determined by experiment from the rate law of the reaction. It is the sum of the exponents in the rate law equation. Molecularity, on the other hand, is deduced from the mechanism of an elementary reaction, and is used only in context of an elementary reaction. It is the number of molecules taking part in this reaction.
