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.
