Consider the following reaction: [Cr(H2O)5(SCN)]2+  +  Yn-  -->  [Cr(H2O)5Y](3-n)+  +  SCN- Which statement is true if this reaction occurs via a dissociation mechanism? Group of answer choices Changing the incoming ligand, Yn-, will have a large effect on the rate constant. The first step of the mechanism is the addition of the Yn- ligand to form a 7-ccordinate intermediate, [Cr(H2O)5(SCN)Y](2-n)+ Changing the incoming ligand, Yn-, will have very little effect on the rate constant. It is impossible for this reaction to occur via a dissociation mechanism.

A student prepared three nickel samples in the lab but forgot to label them. The samples that were prepared were [Ni(H₂O)6]²+, [Ni(NH3)6]²+, and [Ni(H₂NCH₂CH₂NH2)3]2+. The sample vials were coloured violet, blue, and green. Which sample corresponded to which coloured vial? [Ni(H2O)%]2+ = green; [Ni(NH3)%]2+ = blue; [Ni(H2NCH2CH2NH2)3]2+ = violet [Ni(H₂O)6]²+ = green; [Ni(NH3)612+ = violet; [Ni(H₂NCH₂CH₂NH2)3]²+ = blue [Ni(H2O)%]2+ = violet; [Ni(NH3)%]2+ = green; [Ni(H2NCH2CH,NH2)3]2+ = blue [Ni(H2O)%]2+ = violet; [Ni(NH3)%]2+ = blue; [Ni(H2NCH2CH2NH2)3]2+ = green O [Ni(H₂O)6]²+ = blue; [Ni(NH3)6]2+ = green; [Ni(H₂NCH₂CH₂NH2)3]²+ = violet
