Rate = d[P] dt = k[R]x. In other words, the rate of the reaction can be defined as the change in product concentration over changing time.
WebStep 1. The carbon-bromine bond is a polar covalent bond. The cleavage of this bond allows the removal of the leaving group (bromide ion). When the bromide ion leaves the tertiary butyl bromide, a carbocation intermediate is formed. As mentioned earlier, this is the rate-determining step of the S N 1 mechanism.
