Consider the following anation reaction [CoX₂(H₂O)BR](NO₃)₂ + KBr -> [CoL₂Br₂](NO₃) + KNO₃

Given the following information :

V activation = 6 cm³ mol-1

S activation = 70 j mol -1 k-1

rate = [[CoX₂(H₂O)BR](NO₃)₂] [KBr]

k ----------------------------------------------

[KBr] + [H₂O]

Where X = 1,2-tetramethylethylenediamine

(i) if - [CoX₂(H₂O)BR](NO₃)₂ was to be dissolved in water, would you expect racemization to occur? why? show mechanisms to support your answer

(ii) Would you expect racemisation to occur faster or slower if the X was changed to 1,2-ethylenediamine? your explanation should make use of the activation/rate information given above
