    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.
