※ 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 ...................................................................... -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 203.73.104.25
