  1. Chemical equilibrium constantC1formal

    A numerical value that expresses the ratio of concentrations of products to reactants at chemical equilibrium, at a given temperature.

    zh平衡常数

    • The equilibrium constant for the reaction was calculated to be 4.5.
    • Changing the temperature alters the value of the equilibrium constant.
    • A large equilibrium constant indicates that the reaction favors the products.
