When tert-butyl bromide is heated with an equal amount of ethanol in an inert solvent, one of the products is ethyl tert-butyl ether.
(a) What happens to the reaction rate if the concentration of ethanol is doubled?
(b) What happens to the rate if the concentration of tert-butyl bromide is tripled and the concentration of ethanol is doubled?
(c) What happens to the rate if the temperature is raised?
This is a type of SN1 reaction, here the rate of reaction is influenced by the concentration of reactant i.e tert-butyl bromide.
As the concentration of the reactant increases the rate of product formation will also increases.
