Bromomethane is converted to methanol in an alkaline solution. The reaction is first order in each reactant. CH3Br(aq)+OH−(aq)→CH3OH(aq)+Br−(aq)

Write the rate law

How does the reaction rate change if the OH− concentration is decreased by a factor of 5?

What is the change in rate if the concentrations of both reactants are doubled?
