The reaction rate for the reaction
`[PtCl_4]^(2-) + H_2O = [Pt(H_2O)Cl_3]^(-) + Cl^-`
was measured as a function of conccntrations of different species. It was observed that
`(-d[[PtCl_4]^(2-)])/dt = 4.8 xx 10^(-5) [[PtCl_4]^(2-)] -2.4 xx 10^(-3) [[Pt(H_2O)Cl_3]^-][Cl^-]`
where square brackets arc used to denote molar concentrations. The equilibrium constant `K_c` = ___________. (Nearest integer)

The rate of reversible reaction (change in concentration per second): PrCl_(4)^(2-)+H_(2)OhArrPt(H_(2)O)Cl_(3)^(-)+Cl^(-) , was observed at 0.3 ionic strength at 25^(@)C and noticed that (Delta[PtCl_(4)^(2-)])/(Delta t)=3.9xx10^(-5)[PtCl_(4)^(2-)]-2.1xx10^(-3)[Pt(H_(2)O)Cl_(3)^(-)][Cl^(-)] Calculate: ( a ) Rate constant for forward and backward reaction. ( b ) The equilibrium constant for the complexation of fourth Cl^(-) at 0.3 ionic strength.

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.
