A reaction is said to be diffusion controlled when it occurs as fast as the reactants diffuse through the solution. The following is an example of a diffusion controlled reaction.
The rate constant for this reaction is 1.4x1011 M-1s-1 at 25oC and the reaction obeys the following rate law.
rate = k(H3O+)(OH-)
Calculate the rate of reaction in a neutral solution (pH=7.00).
