Arrhenius reaction rate for H20(l) and H20(g)
Arrhenius reaction rate for H20(l) and H20(g)
(OP)
I need to find the Arrhenius reaction rate for H2O liquid and H2O vapor (in equilibrium). I'm having difficulties in finding this mostly since its a reaction rate for a change in phase. If anyone can give me a clue where to find something like this please let me know.
Thanks,

Thermodynamics will dictate equilibrium. Clausius-Clapeyron Equation is likely closer to your needs? Why not use steam tables to find equilibrium states?
Rate of change for the physical phase change process will be governed by heat transfer and thermodynamic principles.
Let us know what you are trying to do and perhaps we could help further. Good luck.

I realize that the change from liquid water to liquid vapor isn't a chemical reaction. What I'm looking for is the rate of change of the phase change process from H2O(g) to H2O(l) or visa versa in the Arrhenius expression format. I have been told that it has been expressed this way in some texts, possibly a combustion text, but no one can point me back to where they found it. I was hoping that someone here might have seen this as well and know where to find it. Thanks again for your help.
