The approach to the following equilibrium was observed kinetically form both directions: [PtCl_(4)]^(2-) +H_(2)O hArr [Pt(H_(2)O)Cl_(3)]^(ɵ)+Cl^(ɵ) At 25^(@)C it was found that at 0.3 inoic strength - (Delta [PtCl_(4)]^(2-))/(Delta t) = (3.9 xx 10^(-5)s^(-1))[PtCl_(4)]^(2-) - (2.1 xx 10^(-3) L mol^(-1) s^(-1))[Pt(H_(2)O)Cl_(3)]^(ɵ)[Cl_(3)^(ɵ)] What is the value of k for the complexation of the fourth Cl^(ɵ) by Pt(II) at 0.3 ionic strenght.
