5. Based on the AGⓇ =-RT In K expression, would you predict that AgCl(s) dissolving into Ag+ (aq) + CI+ (aq) [Ksp = 1.8x10-1') is a spontaneous process? Would you expect Co3+ (aq) +6NH3(aq) forming the [CO(NH3)6]+ complex ion [Kp = 4.5x1033] to be a spontaneous process? How does the magnitude of the equi- librium constant relate to the AGº? If a saturated solution of calcium hydroxide is prepared and its Ksp is determined, how can the AG = AGº+RT...
