How does kinetics relate to equilibrium?
Hence there is a fundamental relationship between chemical kinetics and chemical equilibrium: under a given set of conditions, the composition of the equilibrium mixture is determined by the magnitudes of the rate constants for the forward and the reverse reactions.
Is chemical kinetics related to equilibrium?
Kinetics, equilibrium, and the reaction coordinate diagram (advanced topic). Chemical equilibrium is the state of constant composition attained when opposing reaction rates become equal. There is an essential relationship between reaction rates and chemical equilibrium, one that we can describe quantitatively.
What is physical chemistry kinetics?
chemical kinetics, the branch of physical chemistry that is concerned with understanding the rates of chemical reactions. It is to be contrasted with thermodynamics, which deals with the direction in which a process occurs but in itself tells nothing about its rate.
What is equilibrium in physical chemistry?
Physical equilibrium is defined as the equilibrium which develops between different phases or physical properties. In these processes, there is no change in chemical composition. It represents the existence of the same substance in two different physical states.
How do you compare chemical kinetics with chemical equilibrium and thermodynamics?
Thermodynamics focuses on the energetics of the products and the reactants, whereas kinetics focuses on the pathway from reactants to products. Table 18.4 “The Relationship between ” gives the numerical values of the equilibrium constant (K) that correspond to various approximate values of ΔG°.
Is equilibrium related to reaction rate?
Equilibrium is when the rate of the forward reaction equals the rate of the reverse reaction. All reactant and product concentrations are constant at equilibrium.
What is the difference between thermodynamics and kinetics?
Thermodynamics tells us what can occur during a process, while kinetics tell us what actually occurs. Some processes, such as the conversion of diamond to graphite, are thermodynamically favored but kinetically unfavored. In these cases, the processes do not occur to any measurable extent.
What are the types of equilibrium?
There are three types of equilibrium: stable, unstable, and neutral.
