化学图象题是利用直角坐标系来描述有关化学量间函数关系的一种题型。本文就图象题的几种常见类型,通过例题分析,简述其解答方法。一、可逆反应中物质浓度与时间的关系例1.A和B在溶液中进行如下可逆反应:A+B(?)AB。反应开始时,溶液中只有A和B,反应过程中A、B、AB的物质的量浓度随时问的变化曲线图正确的是( )。
The chemical image question is a question type that uses Cartesian coordinates to describe the relationship between chemical quantities. In this paper, several common types of image questions are analyzed through examples and their solutions are briefly described. First, the relationship between the material concentration and time in the reversible reaction Example 1. A and B The following reversible reaction in the solution: A + B (?) AB. At the beginning of the reaction, only A and B were present in the solution. The curve of the concentration of substances A, B, and AB during the reaction was correct at any time ().
