`S_(N^(1))` reaction is a first order nucleophilic substitution e.g.
`CH_(3)-overset(CH_(3))overset(|)underset(CH_(3))underset(|)C-Br+H_(2)Oto CH_(3)-overset(CH_(3))overset(|)underset(CH_(3))underset(|)C-OH+HBr`
The concentration of nucleophile does not appear in the rate law expression.
Reaction rate k[RX]
In a mulptistep organic reaction , the rate-limiting step is the slowest step . Rate determining step is represented by the following energy level diagram:
A reaction energy level diagram for an `S_(N^(1))` reaction .The rate limiting step is spontaneous dissociation of an alkyl halide to give a carbocation intermediate:
