What is the equilibrium constant (Kc) for the overall reaction if K’c = 4.2 x 10^-7 and K’’c = 4.8 x 10^-11? Show the computation steps.
Understand the Problem
The question is a detailed exposition on multiple equilibria in chemical reactions, specifically focusing on the calculation of equilibrium constants for various systems, particularly diprotic and polyprotic acids. It provides examples of how to compute the equilibrium constant (Kc) using given values, explains the principles governing equilibrium constants, and offers methods to determine equilibrium concentrations. The user may need to perform specific calculations based on this theoretical groundwork.
Answer
2.016 x 10^-17
The final answer is 2.016 x 10^-17
Answer for screen readers
The final answer is 2.016 x 10^-17
More Information
When dealing with subsequent reactions, the equilibrium constant of the overall process is the product of the equilibrium constants of the individual steps.
Tips
A common mistake is to forget that the equilibrium constant for sequential reactions is multiplicative rather than additive.
