Give handwritten answer of the following question.

The following chemical equations shows the stepwise formation constant expression
K) of cach ox replaces two water.
Fel + C2042
[Fe(C,O4) + C20,2 - [Fe(C2O42)
|Fe(C:04)2] + C0
- |Fe(C204)"
|Fe(ox); |
(Fe(ox)"!
K,
[Fe"| |ox|
(Fe(ox),"|
K =
|Fe(ox)| |ox|
[Fe(ox), |lox)
a) Write the overall formation constant experssion (Kr or Ba) demonstrating that the
Ki is given by the product of the three stepwise constants.
b) The value of successive stability constants decreases from KI to Ka. Why?
c) The complex (Fe(C,O43) has high Ki value, which is about 2 x 1020, Give reason
based on its structure.
