 (A)the molecules of H2 have the hightest average velocity
 (B)CH4 and NH3 have the closest values of PV/RT
 <C>all four gase have the same average kinetic energy
 <D>all four gase have the same number of molecules
 <E>O2 strays away most from the ideal gase behavior among the four
     (B)應該是錯的(D)應該是對

7.When an exothermic reaction is carried out in a calorimeter,which of the

 <B>3s and 3p do not exist
 <C>transition between  n=3 and 4  absorbs visible light
 <D>n=0 is not allowed
 <E>UV light can ionize the election
 主要想問(C)和(E)

13.Ozonecanabosrb ultraviolet light to decompose to oxygen. The rare law for
  this reaction has been determined as Rate=K[O3]2 / [O2]
 <a)Derive a mechanism that explains this rate law.
 (b)Write the stoichiometric equation(劑量式) for this reaction.
 (c)Draw an energy profile for this reaction and specify the activation energy
 in the profile.
 (d)NO is a free radical. Explain why NO can accelerate the ozone depletion?
這題我不太懂題目要問什麼


謝謝有耐心的善心好人看完我的問題
拜託會的人教我
不用全部回答也可以
91年的題目,我沒有正確答案
能給我解答嗎?
我想應該都是複選
謝謝唷~~
