1.
The enthalpy of vaporization for water is 40.7 KJ/mol at 1atm
then what is the boiling point of water at 475 torr?
(Tb=100度C R=8.314 J/K mol)
答案: 87.1度c
是用delta S= deltaH/Tb 开头吗0.0 完全没有头绪 囧
2.
Given the equation:2 NOCl2(g) <=>2NO(g) + Cl2(g)
the equilibrium constant = 0.015 at 115度C
计算Kp=? 答案:0.478
我题意看不太懂... 平衡常数题目不是有给了?
我一开始以为是要用Kp=Kc(RT)^n
抱歉 一直麻烦大家....
感谢解答
