92年 16.Which designation has the largest number of atomic orbitals? (A)n=3 (B)7f (C)n=6,l=5 (D)n=7,l=3.ml=-3 (A)有9個軌域 (B)7個 (C)11個 (D)1個軌域 為什麼答案不是(C) 而是(B) 93年 2.Consider the aqueous solutions containing 0.1M of the following substances, which of them would have good conductivity? (A)CH3NH2 (B)CH3COOH (C)HCIO4 (D)Ca(OH)2 (E)NH4Br 5.Four identical 1.0L flasks containing H2, CH4,NH3, and O2,respectively,each at 25度C and 1atm pressure,which of the following statement is correct? (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 following statement is correct? <A>q(H2O) < 0 <B)ΣH(products) < ΣH(reactants) <C>the temperature of water decreases <D>ΔH(reaction) < 0 <E>the reaction takes place spontaneously (B)(D)應該對 8.Considering the atomic structure of hydrogen, which of the following staement is correct? <A>3s and 3p are equal in energy <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~~ --
