部编高中化学课本中关于平衡常数的意义是这样叙述的:“K值越大表示反应达到平衡时生成物浓度对反应物浓度的比值越大,也就是反应进行得更完全些,反应物的转化率也越大。反之,K值越小表示反应进行的程度越小,反应物的转化率也越小。”
The significance of the equilibrium constants in the Department of Chemistry textbooks for senior high schools is described as follows: “The higher the value of K, the greater the ratio of the product concentration to the reactant concentration when the reaction reaches equilibrium, that is, the reaction proceeds more completely. The higher the conversion rate, the smaller the K value is, the smaller the reaction is and the smaller the conversion of the reactants.
