=92C= 3. The reaction NO(g)+O3(g) → NO2(g)+O2(g) was studied by performing the flooding technique. When [O3]=1.0*10^14 mole/cm3,the change of [NO] with time is shown in Table 1. When [NO]=2.0*10^14 mole/cm3,the change of [O3] with time is shown in Table 2. Table 1 Table 2 ------------------------------------------------------------------------- Time [NO] Time [O3] (ms) (mole/cm3) (ms) (mole/cm3) 0 6.0*10^8 0 1.0*10^10 100 5.0*10^8 50 8.4*10^9 500 2.4*10^8 100 7.0*10^9 700 1.7*10^8 200 4.9*10^9 1000 9.9*10^7 300 3.4*10^9 (a)Using the graphs to determine the rate order with respect to [NO] and [O3]? (b)Determine the rate law and evaluate to rate constant for this reaction. (c)Propose a mechanism and explain how it can match with the experimental data. 第一题级数我是用半生期去看，然後比例大约都是1，所以两个的级数我都写1， 但是不知道是不是这样看 第二题用他给的[NO]和[O3]浓度用一级去代然後列出式子去算k 第三题不知道要怎麽写 =93年= 2.(a)Discuss what happens to the energy level for an electron trapped in a one-dimensional box as the length of the box increases. (b)Which has the lowest(ground-state)energy,an electron trapped in a one-dimensional box of the length 10^-6 or one with 10^-10? 3.One of the biggest challenges in preparing fuel for nuclear power plants is to separate the isotopes of uranium. (a)Why is it not possible to separate the isotopes of uranium by chemical means? (b)How are the isotopes of uranium separated? 第二题不晓得在问甚麽，第三题也只写出用慢中子撞击去分开，其他不知道要怎麽回 答 以上 麻烦版友帮忙解惑 小女子感激不尽!!! --
