Consider the hypothetical cations, A and Ct and anions, B and D. Calculate the AG when 20.0 mL of 0.25 M AB (aq) is mixed with 15.0 mL of 0.30 M CD (aq) to form the precipitate, AD (s) at 25C. Ksp of AD is 3.8 x 10-11 at 25C -49.5 kJ 69.3 kJ O 38.5 kJ O not enough given to answer the problem O-58.8 kJ Calculate the value of the equilibrium constant at 298 K for the reaction happening at 263 K that is accompanied by 4,Sof 153.4 J K 1 mol-1 and 4, Hof 85.6 kJ mol-1. Is this reaction spontaneous? O K=1.22 1022 spontaneous O K = 224, non-spontaneous OK - 1.96 10-56, non-spontaneous X OK -118, spontaneous OK -1.25 1073 spontaneous
