Why can

WebSolution. The correct options are. B Order can be negative. C Order of a reaction can’t be predicted by stoichiometry of reaction. D First order reaction may be complex or elementary reaction. A complex reaction could have an order of two, so it is not necessary for all second order reactions to be bimolecualr elementary reactions. WebThe reaction is first order with respect to NO2 and first-order with respect to CO. This is consistent with a single-step bimolecular mechanism and it is possible that this is the mechanism for this reaction at high temperatures. At temperatures below 225 °C, the reaction is described by a rate law that is second order with respect to NO2: how to sign the word deaf

WebThis can be explained considering that the reaction occurs in 2 steps: NO + Br2 ----> NOBr2 ( The first reaction is the slow step, therefore it dictates the rate) NOBr2 + NO -----> 2NOBr ----------------------------------------- 2NO + Br2 ----> 2NOBr ( The sum of the 2 reactions above gives the original reaction) Comment ( 5 votes) Upvote Downvote Webfirst order reaction. C. second order reaction. D. bimolecular reaction. Medium. Open in App. Solution. Verified by Toppr. Correct option is A) A reaction involving two different reactants can never be unimolecular reaction. This is because, for the reaction to occur, atleast two different molecules must collide.

WebA bimolecular reaction is second-order because its rate is proportional to the rate at which the reactant species meet, which in turn is proportional to their concentrations. Therefore, if we believe that a reaction is a single-step, bimolecular process, we can write down the rate law (and then Web3 (third) L 2 mol −2 s −1. The units in this table were derived using specific units for concentration (mol/L) and time (s), though any valid units for these two properties may be used – for example: M/hour, M/min or g L -1 s -1 are all valid units for rate.
