九年级SCIENCE课本第68页一道实验题,我看不懂也不会作,哪个英文好的人帮我翻译一下,上学的朋友帮我解答一下,谢谢谢谢!!!!
是关与ＣＨＥＭＩＣＡＬ ＲＥＡＣＴＩＯＮ中温度和反应速度的
是一道关于曲线图的题
假如你作一个曲线图，你用的温度是０度，２０度，５０度，９５度
你朋友的度数是０度，３０度，７０度，８０度
问题是（我不会翻译，请你帮我翻译）
1,how do you think your two graphs would be different?
2,how would you expect them to be the same ?

you have two rate vs. T curves, and you wanna comapre them.
basically, the ln (or log) of the reaction rate is linear propertional to the reciprocal of temperature (kelvin) by the Arrenhenius equation R=A.EXP(-E/KT). so rate increases expenetially to T, If the two cures have the same activation energy E, and if at 0 degree they have the same reaction rate, then theses two curves should be exactly the same. If the activation energies of the two curves are different, then the two curves should have an intersection, at the corresponding temperture of that intersection they have the same reaction rate.
1. Coz the different envirenment the experiment were taken, the different point of the Tem. the different rate they appeared add the error made by different person, as a result, the two graphs should be different.
2.Make another new graph according to all the 8 points u and ur classmate have got, coz actually there should be only one graph, and all ur 8 points shoud be on the graph

如两条曲线有差异的话，它们的差别是什么？（注意，这里用的是虚拟语气）
2,how would you expect them to be the same ?
在何种条件下，它们会重合？
Let's suppose that my curver is called as A curve, and the curve of my friend is called as B curve,
Generally, as the temperature rising, the reacting speed will rises with it. The shape of curves depends on how fast the reacting speed i.e. we can judge it by the temperature nodes.
For A curver：since the temperature nodes are 0,20,50 and 95, we can judge that during [0,20] is a period that the reaction is quite active, and in [20,95], the reaction speed is slow down. i.e. the curve is quite steep in [0,20],but growing up gently in [20,95]. ---- A curve may be a convex curve.
B curve：the recorded nodes are 0，30，70，and 80，so we can judge that it is very smooth in [0,70], and then becomes very steep in [70,80]. Consequently it may be a concave curve which ascends smoothly in [0,70] but becomes very steep in [70,80].
these two curves become the same while the reacting speed are the same at the temperature of 0，20，30，50，70，80，and 95.
