1.A solution is prepared by mixing 5.81g acetone (C3H6O, molar mass = 58.1 g/mol) and 11.9 g chloroform (HCCl3, molar mass = 119.4 g/mol ). At 35度C, this solution has a total vapor pressure of 260. torr. What is the expected vapor pressure ? Is this an ideal solution? Explain why. The vapor pressures of pure acetone and pure chloroform at
35度C are 345 and 293 torr, respectively.
2.The gas-phase reaction between methane and diatomic sulfur is given by the equation
CH4(g)+2S2(g)→ CS2(g)+ 2H2S(g)
At 550度C the rate constant for this reaction is 1.1L/mol *s, and at 625度C the rate constant is 6.4 L/mol *s, Using these values, calculate , Ea for this reaction . (ln 5.82=1.76)
不好意思 您那段英文解釋的部份 可以中文講意嗎>"<感謝您~~~
