Compare and rationalize the rate constants for the aquation reactions of the following trans-cobalt(III) complexes:
[Co(NH3)Br(en)2]2+ + H2O ? [Co(NH3)(H2O)(en)2]3+ + Br- k = 1.2 x 10-6 s-1
[CoBr2(en)2]+ + H2O ? [Co(H2O)Br(en)2]2+ + Br- k= 1.4 x 10-4 s-1
the water molecules can be easily replaced bromine in the second complex very fast than the first complex.this we can be explained based on the rate constant values higher rate constant represent faster the reaction.The second aqua complex formation has higher rate constant value
