※ 引述《kijhao (。)》之銘言：
: We can calculate the percentages of two isomers at equilibrium
: using the equation △E=-R*T*lnK .
: △E is the energy difference between isomers
: R is the gas constant
: T is the Kelvin temperature
: K is the equilibrium constant between isomers
: 請問若已知的數據有△E , R , T , K
: 那要怎麼代公式求存在的百分比?
: 題目如下:
: The energy difference of 3.8 (KJ/mol) between gauche and anti butance
: corresponds to an equilibrium constant Keq of approximately 1.9
: Calculate the percentage of each conformer at equilibrium.
: 感謝各位大大的解答
.......................不對就算了.................................
Ksp=1.9
若兩者平衡
令a=b達到平衡
1-x=x
則1.9=x/(1-x)
求得解離常數
我覺得△E , R , T , K是用不到的
這是我的感覺拉
看看有沒有強者來說說對不對
