电子亲和能/(kJ·mol-1) 59.8 52.7 48.4 141 -844.2 327.9
下列说法正确的是(  )
A.电子亲和能越大,说明越难得到电子
B.一个基态的气态氟原子得到一个电子成为氟离子时吸收327.9 kJ的能量
C.氧元素的第二电子亲和能是-844.2 kJ·mol-1
D.基态的气态氧原子得到两个电子成为O2-需要放出能量
答案 C


(2)若相同条件下,SO2(g)的起始浓度增大到3 mol·L-1,NO2(g)的起始浓度仍为2 mol·L-1,则SO2(g)、NO2(g)的转化率变为多少?
(3)对比(1)与(2)中的数据,增大SO2的浓度,SO2与NO2的平衡转化率如何变化?
(4)试想,增大NO2的浓度,SO2与NO2的平衡转化率又如何变化?
解:(1)当达到平衡状态时,测得容器中SO2(g)的转化率为50%,所以SO2(g)的变化浓度为1 mol·L-1。
SO2(g)+NO2(g)??SO3(g)+NO(g)
  2   2    0   0
  1   1    1   1
