Therefore, the rate will double if the hydroxide ion concentration is doubled, and will decrease by a factor of 4 if the concentrations of both the alkyl chloride and the hydroxide ion are halved. b) This is an SN1 reaction (tertiary), so its rate depends only on the concentration of the alkyl chloride. Therefore, the rate will be unaffected if the concentration of the hydroxide ion is doubled, and the rate will be halved if the concentrations of both the alkyl chloride and the hydroxide ion are halved. 8.50 O a) I + OCCH₃ 126
