27. (14 points) The complex trans-PtCl₂(pip)₂ (pip = piperidine) reacts with NaNO₂ in methanol to form trans-PtCl(NO₂)(pip)₂. The kinetic data for a reaction between a 0.0007 M solution of trans-PtCl₂(pip)₂ and different concentrations of NaNO₂ are given below. The reaction follows the rate law:

(1) (6 points) Write the mechanism for the substitution reaction between trans-PtCl₂(pip)₂ and NaNO₂.
