Question
The value of log K for the reaction A B at 298 K is_______. (Nearest integer) Given : Hº = –54.07 kJ mol–1 Sº = 10 J K–1 mol–1 (Take 2.303 × 8.314 × 298 = 5705)
Answer: .
💡 Solution & Explanation
Go = Ho – TSo Go = – 54070 – 293 x 10 = – 57000 J Go = –2.303 RT log Keq – 57000 J = – 5705 log Keq log Keq = 9.99 = 10
