polydentate ligands result in more stable complex ions?

Question

For the next two questions use the below information:


polydentate ligands result in more stable complex ions
then do monodentate ligands


An example of formation equilibrium for a complex ion in solution is:

Al3+ + 6F− ↔ [AlF6]3− Kf = 5.0 × 10−3


ΔG = −RT ln( Kf )


remember, the more negative the value the of ΔG the more stable
are the products of reaction that are formed




Which of the following are true statements ?


a) en stands for ethylenediamine, a bidentate ligand


b) The subscript f in Kf stands for 'free energy'


c) A very small value of Kf for a chemical reaction in which a coordination complex
is a product would indicate that the complex formed is a relatively stable one


d) A very large value of Kf for a chemical reaction in which a coordination complex
is a product would indicate a relatively small decrease in Gibbs free energy

Answer 1

a only.

Answer 2

are you sereoius??!?!? im sorry yet you're on your guy or woman. my suggestion is that in case you in concern-loose, accomplished concern because of the fact one incorrect question wont kill you. severe college, extra valuable get it appropriate! and in college too.
