What is a dynamic balance?
Dynamic balance is the condition in which the ratio of products to reactants remains constant. The constant product ratio to reactants does not mean that the reaction is quite static or that reactants do not respond to the formation of products and vice versa. The dynamic balance is "dynamic" because there is a constant exchange between reactants and products because the reaction continues to consume reactants to create products and consume products to create reactants. The ratio between products and reactants does not change, because the rate of reaction that prefers the products and speed of the reaction that prefers reactants is the same. The same rates do not lead to a change in the product ratio to the reactant over time, so it is said that the reaction is in balance or stable state.
The reaction must be reversible if it is to achieve any form of dynamic balance. Reversiblreak E is a chemical reaction in which reactants canReact to the creation of products that can respond to each other for the creation of the original reaction components. Reversible reactions often prefer either reactants or products, so even if the reaction can continue in both directions, the reaction tends to produce more than the other. This means that the "position" of the dynamic balance may include more products or reaction components. The "equilibrium constant" is used to describe and to perform calculations related to the position of the balance of the reaction.
Many different variable changes in the chemical reaction can shift the position of dynamic balance. The principle of Le Châtelier provides chemists a general way to think about shifts in dynamic balance. The principle generally states that when stress is placed on a response in balance, the reaction moves in a direction that minimizes a change in balance. If one adds more reactants to the response in balance, the balance moves towards the products and reaches a new balance based on new KOncentration of reactant and product.
Dynamic balance is naturally associated with the speed at which chemical reactions occur. One may think of a dynamic balance as two different chemical reactions. One occurs in the forward direction, with reactants forming products, while the other occurs in the opposite direction, the first reaction products form reactants. Finally, these two reactions settle in balance based on their equilibrium constants. In equilibrium, the reactions forward and reverse reaction occurs at the same speed.
