Consider following reactions:
I. [Co(NH3)6]3+(aq)+6H3O+(aq)⇌[Co(H2O)6]3+(aq)+6NH+4(aq)
The products are favoured in the above reaction:
II. [Co(NH3)6]2+(aq)+6H3O+(aq)→[Co(H2O)6]2+(aq)+6NH+4(aq)
The reaction (II) takes place with H2O in a matter of seconds.
Which is thermodynamically unstable and also kinetically labile?
