基本关系①各物质浓度变化量之比=反应式中的化学计量系数之比②反应物的转化率=其消耗浓度与起始浓度之比③平衡时某组分的体积分数=该组分在平衡混合物中的物质的量分数化学平衡问题的思维方法①“极限思维法”——任何可逆反应均可以看成完全反应和完全不反应的中间状态。我们在求某一物质在平衡状态的浓度取值范围时,常
The basic relationship ① ratio of changes in the concentration of the substance = the stoichiometric ratio of the reaction equation ② reactant conversion = the ratio of its consumption concentration and the initial concentration ③ volume fraction of a component at equilibrium = Balance the amount of material in the mixture Thinking of the chemical equilibrium problem ① “limit of thinking ” - Any reversible reaction can be seen as completely reacted and completely non-reactive intermediate state. We are seeking a substance in the equilibrium concentration range of values, often
