Consider a kinetics study of the following ligand substitution reaction: trans-[Rh(en)2Cl2] + + 2 Y−  trans-[Rh(en)2Y2] + + 2 Cl− When Y− = I−, Br−, and NO2 −, the reaction rate constants are 5.2 x 10-5 , 4.0 x 10-5 , and 4.2 x 10-5 M-1 s-1 , respectively. By which mechanism does this reaction most likely proceed? Justify your answer.

Which statement is true regarding the following reaction? cis-Λ-[Co(en)2Cl2] + OH− --> cis-[Co(en)2Cl(OH)] + Cl− Group of answer choices At high OH- concentrations, the product complex is a Δ isomer. This reaction does not actually take place - instead of en ligands, there must be NH3 ligands. At low OH- concentrations, the product complex is a Δ isomer. The first step of this reaction mechanism is the dissociation of Cl-.
