Problem 21.135c
Textbook Question
Textbook QuestionFormation constants for the ammonia and ethylenediamine complexes of nickel(II) indicate that Ni(en)32+ is much more
stable than Ni(NH3)62+:
(1) <REACTION>
(2) <REACTION>
The enthalpy changes for the two reactions, ΔH°1 and ΔH°2, should be about the same because both complexes have six Ni﹣N bonds.
(c) Assuming that ΔH°2 - ΔH°1 is zero, calculate the value of ΔS°2 - ΔS°1.
