Learn the equilibrium definition in chemistry and study chemical equilibrium concentrations. Explore the types of chemical equilibrium and factors...
Chemical equilibrium exists when a reversible chemical reaction occurs within a closed system, such as a sealed flask, and the rate of the reaction in the forward direction equals the rate of the reaction in the reverse direction. For example: N 2 + 3H 2 ⇄ 2NH 3 . ...
Dynamic equilibrium in chemistry means that reactants are constantly forming products and products are constantly forming reactants. Since the rates of formation are identical, the overall concentration of each chemical species is constant. What does chemical equilibrium mean? In reversible chemical ...
Examples include the balance of forces acting on an object, the distribution of heat in a closed system, or the equalization of pressure in a fluid. In other fields, such as economic, social, chemistry, medical, and psychological domains, what does equilibrium mean? Equilibrium is a state of...
introduced the concept ofequilibriumto acid–base chemistry: this concept states that reversible chemical reactions reach a point of balance, orequilibrium, at which the starting materials and the products are each regenerated by one of the two reactions as rapidly as they are consumed by the ...
Open questions concerning scale-up of structured catalytic packings are discussed on the basis of experiments in the lab and pilot plant scale. Lab scale experiments were modelled satisfactorily with an equilibrium stage approach. In order to perform the scale-up from lab to pilot scale with the ...

Any system indynamicequilibriumtends to reach a steady state, a balance that resists outside forces of change. When such a system is disturbed, built-in regulatory devices respond to the departures to establish a new balance; such a process is one offeedbackcontrol. All processes ofintegration...
Diffusion continues until equilibrium is reached. At equilibrium, concentration is the same throughout the sample. Familiar examples of diffusion are the transport of perfume when it is sprayed in a room or the movement of food coloring in a glass of water. ...
Chemosynthesis has been detected in hydrothermal vents, isolated caves, methane clathrates, whale falls, and cold seeps. It has been hypothesized the process may permit life below the surface of Mars and Jupiter's moon Europa. as well as other places in the solar system. Chemosynthesis can occu...
