新课标在平衡部分的难度有所加大,有传统的平衡移动原理,也有新增的平衡常数。平衡原理的应用也有所拓展,比如新增了难溶物质的溶解平衡。高考中各地考查难度不尽相同,各有特色,本文通过一些典型例题谈谈新课标平衡部分的学习方法与技巧。一、建模学等效模型1:在定温、定容条件下,对于反应前后气体分子数发生改变的可逆反应,只改变起始时加入物质的物质的量,如果通过可逆反应的化学式计量数之比换算成同一旁物
The new curriculum in the balance part of the degree of difficulty has increased, the traditional principle of balanced movement, but also the new equilibrium constant. The application of the principle of balance has also been expanded, such as the new dissolution of a balance of insoluble substances. Exam difficulty throughout the college entrance examination varies, each with its own characteristics, this article through some typical examples to talk about the balance of the new course standard part of the learning methods and techniques. First, the modeling equivalent model 1: at constant temperature, constant volume conditions, for the gas molecules before and after the change in the number of reversible reaction, only changing the initial amount of substance added to the material, if the number of reversible reaction by the formula Converted into the same ratio
