If the activation energy for a given compound is found to be 103 kj/mol, with a frequency factor of 4.0 × 1013 s-1, what is the rate constant for this reaction at 398 k? 2.5 × 107 s-18.2 s-13.9 × 1010 s-11.2 s-11.7 × 1010 s-1

Water ionizes by the equation h2o(l)⇌h+(aq)+oh−(aq) the extent of the reaction is small in pure water and dilute aqueous solutions. this reaction creates the following relationship between [h+] and [oh−]: kw=[h+][oh−] keep in mind that, like all equilibrium constants, the value of kw changes with temperature.
