2005年高考较为注重考查学生对图表信息的分析和处理能力,2006年高考将更为着重对此考查。【例题】在密闭容器中,由一定起始浓度的氙(X e)和F2反应,可得到3种氟化物。各种生成物在平衡体系内的分压与反应温度的关系如右图所示(已知气体的分压之比等于物质的量之比)。(1)420K时,
The college entrance examination in 2005 pays more attention to examine students’ ability to analyze and process chart information. In 2006, the college entrance examination will focus more on this examination. Example: In a closed vessel, three fluorides can be obtained by reacting Xe with a certain initial concentration (Xe) and F2. The relationship between the partial pressures of various products in the equilibrium system and the reaction temperature is shown in the right figure (the ratio of the partial pressures of the known gases is equal to the ratio of the amounts of the substances).
