化学平衡一直是高考的重点与热点,在高考试卷中具有很好的稳定性,通过分析高考试题,可以很好地把握高考的考点和命题方向,在复习过程中能够做到有的放矢.一、等效平衡例1已知:H2(g)+I2(g)2HI(g);ΔH<0.有相同容积的定容密闭容器甲和乙,甲中加入H2和I2各0.1 mol,乙中加入HI 0.2 mol,相同温度下分别达到平衡.欲使甲中HI的平衡浓度大于乙中HI的平衡浓度,应采取的措施是()(A)甲、乙提高相同温度(B)甲中加入0.1 mol He,乙不变
Chemical equilibrium has always been the focus of college entrance examination and hot spots in the college entrance examination papers with good stability, through the analysis of college entrance examination questions, you can well grasp the test entrance and proposition direction, review process can be targeted. Equilibrium example 1 is known: H2 (g) + I2 (g) 2HI (g); ΔH <0. A constant volume closed container with the same volume A and B, Add HI 0.2 mol, at the same temperature, respectively, to achieve a balance. To make a balance of HI in the B concentration is greater than the equilibrium concentration of B HI, the measures should be taken (A) A, B to increase the same temperature 0.1 mol He, B unchanged
