Question

1 What is the difference between the preponderant reaction Vs more advanced reaction?(how to differentiate between them)
2 to say that a reaction is preponderant, Its equilibrium constant must be greater than other reactions' K. By 100 or 1000 times?

Answer 1

1)if the reaction constant is greater than unity, then they say that direct statidium is predominant and vice versa.
2)if the reaction rate constant is 100 times greater, then this reaction will already be predominant.
The notion of a more advanced reaction is not found in textbooks on chemical kinetics and thermodynamics
