中兴96考古题的
8. A centain reaction at equilibrium has more moles of gaseous products than
of gaseous reactants.
(a)Kc~Kp (b)Kc>Kp (c)Kc=Kp (d)Kc<Kp
依我的认知 Kp或是Kc都是平衡常数的一种 就这一题而言 会有大小之分吗?
还是其实有分别呢?
10. Which gives the more concentrated solution?
(a)KNO3 in H2O (b)KNO3 in CHCl3 (c)KNO3 in CCl4 (d)KNO3 in diethyl ether
这一题是在问什麽? 还有那个"concentrated solution"是什麽?
19.Which substance will have the highest entropy?
(a)Butane (b)Isobutane (c)Isopentane (d)Pentane (e)Neopentane
entropy 如何判断高低呢? 是根据什麽吗?
31.Which of the following sets is not iso-electronic ions?
(a)F-,Na+ (b)O2-,Mg2+ (c)Li+,F- (d)Na+,Mg2+
这题是问不具孤电子的离子吗? 这样要怎麽判断呢?
请求高手解答~ 感激不尽
