I need experimental PROCEDURE for this lab experiment

Determining the rates of electron transfer between the excited state of
Ru(bipy);* and Cu and Fe metal ions
2+

Expert Solution

Step 1

Given:-

Determining the rates of electron transfer between the excited state of
Ru ${(b i p y)}_{3}^{2 +}$ and Cu and Fe metal ions

Step 2

Solution:-

The quenching of Ru ${(b i p y)}_{3}^{2 +}$ by $C u_{2} c^{2 +}$ and the data were plotted with stern volume equation.

The plot showed a break and divides into 2 region which is < 0.5 and > 0.5 $C u_{2} c^{2 +}$

Ru ${(b i p y)}_{3}^{2 +}$ molar ratio the quenching above the 0.5 $C u_{2} c^{2 +}$ , Ru ${(b i p y)}_{3}^{2 +}$ was slower $(330 \times 10^{- 6} m^{- 1} s^{- 1})$

than the quenching rate reaction will be below 0.5 ratio $(387 \times 10^{- 6} m^{- 1} s^{- 1})$
