WebA bimolecular reaction involves collision of two particles (molecules or atoms) to produce an activated complex. NO (g)+O2 (g) NO3 (g) 2NO2 (g) N2O4 (g) O3 (g)+O2 (g) 2O2 (g) the following elementary reactions are bimolecular 2HI→H2+I2 NO2+CO→NO+CO2 Bimolecular reactions involve two reactant molecules or atoms. 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. 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.
