1) What happens to the kinetics of an SN1 and SN2 reaction when the substrate concentration is doubled? A) The $S_{N}1$ doubles, while the $S_{N}2$ is unchanged B) The $S_{N}1$ is unchanged, while the $S_{N}2$ doubles C) Both $S_{N}1$ and $S_{N}2$ are unchanged D) Both $S_{N}1$ and $S_{N}2$ double E) SN1 Quadruples while the $S_{N}2$ doubles
