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. WebThe reaction is first order with respect to NO 2 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 NO 2:

"WebThe reaction rate is second order, because it's influenced by both the alkyl halide and the base (bimolecular). Because the E2 mechanism results in the formation of a pi bond, the two leaving groups (often a hydrogen and a halogen) need to be antiperiplanar. " - Bimolecular second order reaction
