Can any body help me out to find Activation energy of adsorption and in that rate constant?

i am confused ........please help me out?

thanks

i want to find the Diffusion coefficient of SDS molecules and with polymer mixture, which is as

Da = D exp[-Ea/RT]

i am confused how to determine the (-Ea), which is termed as activation energy.

I know the D, as found from Static surface tension measurement, R and T. But i am not getting Clue to find (-Ea).

their are methods given on Wikipedia but for gases..............Now can you guide me?

Ok, has this anything to do with Nuclear or particle physics? =)

Mods, move to Atomic physics forum.

No,

i am doing adsorption of sds on some solid particles with polymers like Al, TiO2
etc

malawi_glenn is right about this (as many other things :P) this is not nuclear physiscs/hep
hope this might help u though.. http://www.science.uwaterloo.ca/~cchieh/cact/c123/eactivat.html

i got it.

i was confused.........but the link is god enough to elaborate and remove my confusion.
