Question

92 H (aq) F (aq), AG JAGO +RT ln HFaq0 [HF] (8.3145 JIK mol (298 K) ln(7.2 x10 1.8 x 10 Jlmol RT ln K. AGO a. The concentrations are all at standard conditions, so AG FAG 1.8 x 10 Jmol (Q 1-0 and ln Q 00. Because AG is positive, the reaction shifts left to reach equilibrium. (2.7 x -2 2 10 b. AG 1.8 x 104 J/mol (8.3145 J/K.mol)(298 K)In 0.98 AG* 1.8 x 104 J/mol 1.8 x 104 J mol 0 AG 0. so the reaction is at equilibrium (no shift). -512 (1.0 x 10 c. AG 1.8 x 10 Jlmol 8.3145(298 K)In 1.1 x 10 mo shifts right 1.0 x 10 7.2 x 10 (0.27) d. AG 1.8 x 104 8.31450298) ln 1.8 x 104 1.8 x 10 0; 0.27 at equilibrium 1.0 x 10 (0.67) e. AG 1.8 x 104 8.314502980 ln 2 x 103 J/mol; shifts left 0 52
