這是轉學考考古題,有幾題想要請教大家,謝謝!!!!
1.Which of the ions can only exist in high spin state in forming octahedral
complex?
(A)Cr2+ (B)Mn4+ (C)Fe3+ (D)Co3+ (E)Ni2+
2.Which of the following octahedral complexs has the largest crystal field
splitting energy?
(A)[Cr(H2O)6]3+
(B)[Cr(SCN)6]3-
(C)[Cr(NH3)6]3+
(D)[Cr(CN)6]3-
(E)[Cr(en)3]3+
3.The dissociation of hydrogen H2(g)<=>2H(g)....<=>是可逆方向符號
(A)is spontaneous at any temperature
(B)is spontaneous at high temperature
(c)isspontaneous at low temperature
(D)is nonspontaneous at any temperature
