标题[学科] 亨利定律
时间Wed Jul 7 18:15:48 2010
The solubilliry of O2 in water is 0.590 g/L
at an oxgen pressure of 15 atm (O2=32)
What is the Henrys law constant for O2(in units of L-atm/mol)?
A:8.14*10^2
我只知道 W=KP W代所容气体重 P代所容气体分压
但是这样代答案不对= =
感谢解答~~~

1F：推 jugi:单位 07/07 18:38
2F：推 Rexxx:我算 ki = 4.53*10^4 (atm) 就算换算成题目要的单位也只会更 07/07 21:32
3F：→ Rexxx:大咧... = =" 07/07 21:32
4F：推 Rexxx:啊... 4.53*10^6 (atm) = 815 (L-atm/mol) = = 答案没错 07/07 21:39
5F：→ Rexxx:btw 用热力学 气液平衡式 Pi = xi*C*ki (for dilute sol'n) 07/07 21:42
6F：→ Rexxx:可算出题目要求单位之ki, xi:莫耳分率, C:总浓度,Pi为氧分压 07/07 21:44
