For the complex ML₂, stepwise formation constants for

$\begin{matrix} M + L & ⇌ & ML \\ ML + L & ⇌ & {ML}_{2} \end{matrix}$

are 4 and 3. Hence, overall stability constant for

$\begin{matrix} M + 2 L & ⇌ & {ML}_{2} \end{matrix}$ is:

Options:

Answer:

Solution:

$\begin{matrix} M + L & ⇌ & ML \end{matrix},$ $K_{1} = \frac{[ML]}{[M] [L]} = 4$

$\begin{matrix} ML + L & ⇌ & {ML}_{2} \end{matrix},$ $K_{2} = \frac{[{ML}_{2}]}{[ML] [L]} = 3$

$\begin{matrix} M + 2 L & ⇌ & {ML}_{2} \end{matrix},$ $K_{3} = \frac{[{ML}_{2}]}{[M] {[L]}^{2}}$

K₃= K₁K₂= 12
