化学反应速率、化学平衡的图象是高考高频高点之一,而学生解该类图象试题时无从下手,不会审题,致使丢分严重,现本人就将该类题的解法介绍如下:一、解答速率、平衡图象题的一般思路1.要看清并读懂图象一要看清楚横坐标和纵坐标所表示的物理量;二要看懂线的走向、变化趋势;三要注意变化点,如线是否通过原点,两条线的交点及线的拐点;四要善于借助辅助线(如等温线、等压线);五要看清楚定量图象中有关量的多少。
Chemical reaction rate, chemical equilibrium image is one of the college entrance examination high frequency high, and students solve this kind of image test questions can not start, will not essay, resulting in dropped serious, now I will introduce the solution to these problems are as follows : First, to answer the rate, the general idea of the problem of balanced images 1. To see and read the image to see clearly the horizontal and vertical coordinates of the physical quantity; Second, to understand the trend of the line, the trend of change; Pay attention to the changing point, such as whether the line through the origin, the intersection of two lines and the inflection point of the line; four should be good at using auxiliary lines (such as isotherms, isobars); five to see clearly the amount of quantitative images.
