寫課本習題遇到不知道該怎麼下手,求平衡常數的問題 麻煩大家指點我迷津 The dissociation vapor pressure of NH4CL at 427度C is 608 kpa but at 459度C it has risen to 1115 kpa. 求 (a)equlilbrium constant (b)standard reaction Gibbs energy (c)standard enthalpy (d)standard entropy of dissociation all at 427度C. Assume that the vapor behaves as a perfect gas and that △H and △S are independent of temperature in the range given. 答案:(a) 9.24 (b) -12.9 kJ/mol (c) 161 kJ/mol (d) 248 J/K.mol 謝謝 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 218.172.97.120 ※ 編輯: karena817 來自: 218.172.97.120 (02/16 18:17)

我覺得應該還要有459℃時的平衡常數....這樣才算得出來
