Definition: The difference between the stability constant of ternary complex and summation of all binary complexes.
Purpose: This calculation helps in understanding the relative stability of ternary complexes compared to their binary counterparts.
The calculator uses the formula:
Where:
Explanation: The formula calculates the logarithmic difference between the ternary complex stability and the sum of binary complex stabilities.
Details: Understanding stability constants helps predict complex formation, reaction pathways, and relative stabilities of different complexes.
Tips: Enter the stability constants for the ternary complex (KMAB) and both binary complexes (kMA and kMB). All values must be > 0.
Q1: What does a high km value indicate?
A: A high km value suggests the ternary complex is significantly more stable than the combination of the binary complexes.
Q2: What units are used for stability constants?
A: Stability constants are typically dimensionless as they represent equilibrium constants.
Q3: How precise should my input values be?
A: Use as many significant figures as available, as small differences can significantly impact the result.
Q4: Can this calculator be used for other types of complexes?
A: Yes, the same principle applies to any ternary complex formation from binary complexes.
Q5: What does a km value of 1 mean?
A: A value of 1 indicates no change in stability between the ternary complex and the combination of binary complexes.
