SAT2化学题,涉及可逆反应
Which of the following factors will initially increase the forward rate of the following exothermic reaction:
X Y + heat
1.Increasing the temperature
2.Increasing the concentration of X
3.Adding a catalyst
(A)1,2,and 3
(B)1 and 2 only
(C)2 and 3 only
(D)1 only
(E)3 only
我觉得只有2是正确的,可答案选C,太扯淡了,催化剂不会改变平衡(只会改变反应速率).是不是题出错了?

恩 的确 催化剂不会改变平衡3肯定没有
加温会反方向变题中要求
forward 所以1也不选
加大x的浓度 可行
只有2正确
很显然的问题 有点信心!

SAT2 Sat2 化学题涉及的方面太多,应该怎么办 有关三聚氰胺所涉及的化学题有哪些 SAT2物理题,涉及光Of thefollowing observable phenomena,which can be explained by using the wave model of light,but not the particle model?(C)A region receiving light from two small coherent sources can have points of zero intensity of light.(E)L 问一道SAT2化学题Which sample demonstrates particles arranged in a regular geometric pattern?A CO2(g) B CO2(s) C CO2(l) D CO2(aq) E none of the above我知道很基础啊,我觉得应该选B,不是固体才有规则几何形状吗?但是练习 这第二张里涉及的一些化学的可逆反应方程式. 化学题 . 化学题.. 化学题. 化学题. 【化学】高中的可逆反应有哪些类型?高考燃眉之急!①高中的可逆反应有哪些类型?我想到的是 电离、水解、酯化请问还有吗?请把全部高中涉及的可逆反应的类型全部说出来. 6月份打算考SAT2 在做巴朗的时候发现电学部分有变压器 交流电路 电容器 阴极射线管这些在真正的SAT2物理中真的会出到么 或者说曾经涉及到过么?还有SAT2物理的题型基本上是概念为主呢 还 求两道化学题(找一道涉及溶解度和饱和溶解溶质质量分数的计算题),题好有分!
