DEB The following chemical equations shows the stepwise formation constant expression K) of each ox replaces two water. Fe + C202 - [Fe(C204) [Fe(C204)* + C202 - [Fe(C20)al [Fe(C2O4)2 + C202 [Fe(C204) [Fe(ox)" [Felox), 1 [Fe(ox)":1 K [Fellox] K , [Fefox)*1 [ox] [Fe(ox)lox] a) Write the overall formation constant experssion (Kror Ba) demonstrating that the Kris given by the product of the three stepwise constants. (1 Mark) b) The value of successive stability constants decreases from K, to Ks. Why? (3 Marks) 5 c) The complex [Fe(C204)3P has high Kr value, which is about 2 x 1000. Give reason based on its structure. (2 Mark)
