請教一下
reaction rates of trans-[PtCl2Py2] at 30℃ in methanol as function of [Y],
Y represents the incoming nucleophile.
This plot shows that k-obs = k1 + k2[Y]
What do k1 and k2 represent?

k1 is the solvolysis rate constant.
k2 is the rate const. contrubited from incoming nucleophile.
due to the unchanged conc. of solvent, solvolysis proceeded with
zero-order relationship to solvent (methanol).
if the solvent changed to non-nucleophilic solvent, such as hexane,
you observe k1 = 0.
