For the reaction of Pt(NH₃)₂Cl₂ with water,

the rate law is rate = k[Pt(NH₃)₂Cl₂] with k = 0.090 h^-1.

(a) Calculate the initial rate of reaction when the concentration of Pt(NH₃)₂Cl₂ is

(i) 0.010 M

(ii) 0.020 M

(iii) 0.040 M

(b) How does the rate of disappearance of Pt(NH₃)₂Cl₂ change with its initial concentration?

(c) How is this related to the rate law?

(d) How does the initial concentration of Pt(NH₃)₂Cl₂ affect the rate of appearance of Cl^- in the solution?
