标题[学习] 一题和气体有关的问题
时间Fri Nov 19 23:22:11 2010
A 6.00-L sample of C2H4(g) at 2.00 atm and 293 K is burned in 6.00 L of oxygen
gas at the same temperature and pressure to form carbon dioxide and water. If
the reaction goes to completion, what is the final volume of all gases at 2.00
atm and 293 K?
答案是2.66 L
对於这个答案我实在不知道怎麽算出来的
麻烦好心人士帮我解一下这题
万分感谢!
C2H4 + 3O2 -> 2CO2 + 2H2O
6 6
-2 -6 +4
=4 =0 =4
剩下气体总体积8L
我的算法是这样子
不过和答案差有点远Orz

2F:→ kdjf:我算也是8L 11/20 00:27
3F:→ bnnbnnbnn:8L,可是压力会变大?(3atm) 再变回2atm...5.33L 11/21 01:40
