The stepwise stability constants of a complex are given below. What is its overall reaction stability constant ( ( ₄ ) ) ? ( aligned & M+L M L ; K₁=1.0 10^4 & M L+L M L₂ ; K₂=1.0 10^3 & M L₂+L M L₃ ; K₃=1.0 10^3 & M L₃+L M L₄ ; K₄=1.0 10^2 aligned ) (Overall reaction : (M+4 L M L₄ ) )
Options
- A(1.0 10¹² )
- B(12.1 10^3 )
- C(1.0 10^6 )
- D(1.0 10^8 )
Correct answer
A. (1.0 10¹² )
Step-by-step solution
Given, ( gathered M+L M L ; K₁=1.0 10^4 M L+L M L₂ ; K₂=1.0 10^3 M L₂+L M L₃ ; K₃=1.0 10^3 M L₃+L M L₄ ; K₄=1.0 10^2 gathered ) Overall reaction, (M+4 L M L₄ ) The overall stability constant, ( aligned ₄ & =K₁ K₂ K₃ K₄ ₄ & =1.0 10^4 1.0 10^3 1 10^3 1 10^2 & =1 10¹² aligned )
