4 8 0
X 3X 2X
4-X 8-3X 2X
(2X)/(4-X+8-3X+2X)=0.2
解得X=1 所以剩余氢气为5mol。总物质的量10mol.氢气百分比为50
（2）反应前体积物质的量12.反应后10.体积比1比1，压强比5比6
（3）X/4=0.25（氮气转化率） 3X/8=0.375（氢气转化率）
（4）3x/2min/5L=0.3mol/（L·min）
教你用三段式：
3H2(g) + N2(g) = 2NH3(g)
始 8mol 4mol 0
变 3x x 2x
终 8-3x 4-x 2x
20%=2x/（8-3x+4-x+2x）可得x=1
于是：（1） 混合气体中含氢气的体积百分比。 50%
（2） 反应前后容器内压强之比。 12:10
（3） 氮气和氢气的转化率。 氮气：25%，氢气：37.5%
（4） 求氢气的反应速率。 0.3mol/（L.min）
1设反应了x mol N2
N2+3H2=2NH3
4 8 0
x 3x 2x
4-x 8-3x 2x
同等条件下 物质量百分数 同于体积分数
2x/(4-x+8-3x+2x) *100%=20% 解得 x=1
算出H2体积分数 50%
2压强比等于体积比的正比 体积比=12:10
所以压强比=12:103 转化率等于转化量比起始量 N2 25% H2 37.5%
4反应速率 等于浓度变化量/时间
浓度起始 8/5 最终 5/5=1
v=(8/5 -1)/2 =0.3
不知楼主明白了吗O(∩_∩)O~
直接列3段式（以下单位均为mol/L）
N2(g)+3H2(g) = 2NH3(g)
起始浓度 0.8 1.6 0
转化浓度 x 3x 2x
平衡浓度 0.8-x 1.6-3x 2x
由条件可得2x/(0.8-x+1.6-3x+2x)=2x/(2.4-2x)=20%
所以x=0.2，反应前总物质的量浓度为2.4mol/L,反应后总物质的量浓度为2mol/L
（1）氢气的体积百分比为(0.8-0.2)/2x100%=30%
（2）反应前后容器压强之比=2.4/2=1.2(即6:5)
（3）氮气的转化率为0.2/0.8x100%=25%
氢气的转化率为(0.2x3)/1.6x100%=37.5%
（4）氢气的反应速率为(3x0.2)/2=0.3mol/(L•min)
设氮气转化了X,那么氢气和氨气分别是3X和2X,那么平衡时氮气氢气氨气分别是 4-X,8-3X,2X
再用氨气的体积分数是20%,就可以求出来X是1
那么平衡状态氮 氢 氨 分别是3 5 2
这下就好做了吧
1)50%
2)6/5
3)25%和37.5%
4)0.3mol/(L.min)
