The K, for (Cu(en),1* is much larger than the one for (Cu(NH,),]2+. This difference is primarily an entropy effect. Explain why and calculate the difference between the AS values at 298 K for the complete dissociation of the two complex ions. (Hint: The value of AH is about the same for both systems.)
