Does anyone know where I can find the reaction rate coefficient and design equation for the electrolysis of brine and sodium hydroxide solution? equation 1) $\ce{2 Cl^{–} -&gt; Cl_2 + 2e^{-}}$  

equation 2) $\ce{2 H2O + 2 e^{–} -&gt; H2 + 2OH^{–}}$

These equations are the key reactions in the chlor-alkali process. I want to model a reactor for this process based on a CSTR (continuous stirred tank reactor). However I really need reaction rate coefficients (k values) and design equations. Any help would be much appreciated!
You should look in some kind of reaction rate database, e.g. NIST. An example from the database:
