For a general chemical reaction occurring in solution, aA + bB ⇌ cC + dD. the equilibrium constant, also known as K eq, is defined by the following expression: Keq = [C]c[D]d [A]a[B]b. where [A] is the molar concentration of species A at equilibrium, and so forth.

For an equilibrium mixture of gases, an equilibrium constant can be defined in terms of partial pressure or fugacity. An equilibrium constant is related to the forward and backward rate constants, kf and kr of the reactions involved in reaching equilibrium:

2022年9月3日 · 因为Keq是实验测量的，我们有一种方法来确定ΔG°，即即每个反应所特有的热力学常数。 ΔG °和 ΔG 的单位为焦耳/摩尔（或卡路里/摩尔）。 当 K eq≫ 1， ΔG °大且为负；当 K eq≪ 1， ΔG °较大且为正。

2024年12月8日 · The larger the K, the farther the reaction proceeds to the right before equilibrium is reached, and the greater the ratio of products to reactants at equilibrium. If K is less than 0.001, it is considered small and it will be mostly reactants. If K is greater than 1000, it is considered large and it will be mostly products.

What is equilibrium constant (K eq)? The equilibrium constant may be defined as the ratio between the product of the molar concentrations of the products to that of the product of the molar concentrations of the reactants with each concentration term raised to a power equal to the stoichiometric coefficient in the balanced chemical reaction.

the equilibrium constant, also known as K eq, is defined by the following expression: where [A] is the molar concentration of species A at equilibrium, and so forth. The coefficients a, b, c, and d in the chemical equation become exponents in the expression for K eq.

What is an Equilibrium Constant? A reaction's equilibrium constant, K eq, measures the extent to which reactants are converted to products. Consider the simple reaction equilibrium between A and B: (The symbol ⇌ tells us we are dealing with an equilibrium.) Equilibrium does not necessarily mean that the substances are present in equal amounts.

2021年1月15日 · An equilibrium constant, K eq, is a variable that describes a chemical reaction’s tendency to proceed to completion, meaning all the reactants are converted to products.

Associated with the equilibrium state there is a number called the equilibrium constant, Keq, that expresses the necessary condition on the concentrations of reactants and products for the reaction. Consider the following idealized reaction, where a, b, c and d represent coefficients and A, B, C and D represent reactants and products.

Equilibrium constant (K eq): A ratio that quantifies the position of a chemical equilibrium. When the equilibrium favors reactants Δ G > 0 and K eq < 1. When the equilibrium favors products Δ G < 0 and K eq > 1.
