一、有关化学反应速率的试题1.考查有关化学反应速率的计算例1(北京理综卷)在一定温度下,10 m L 0.40 mol/L H2O2发生催化分解.不同时刻测定生成O2的体积(已折算为标准状况)如表1.下列叙述不正确的是(溶液体积变化忽略不计)()(A)0~6min的平均反应速率:v(H2O2)≈3.3×10-2mol/(L·min)(B)6~10min的平均反应速率:v(H2O2)<3.3×10-2mol/(L·min)
First, the chemical reaction rate of the test 1. To investigate the chemical reaction rate calculation Example 1 (Beijing Science Volume) at a certain temperature, 10 m L 0.40 mol / L H2O2 catalytic decomposition generated at different times measured the volume of O2 ( Has been converted to standard conditions) as shown in Table 1. The following statements are incorrect (negligible change in solution volume) () (A) The average reaction rate 0 ~ 6min: v (H2O2) ≈3 × 10-2mol / (L min) (B) Average reaction rate from 6 to 10 min: v (H2O2) <3.3 × 10 -2 mol / (L · min)
