Discussion Overview

The discussion revolves around determining the activation energy of adsorption and the rate constant associated with it, particularly in the context of the diffusion coefficient of SDS molecules in a polymer mixture. Participants seek clarification on how to calculate the activation energy and its implications for adsorption processes.

Discussion Character

  • Exploratory, Technical explanation, Conceptual clarification

Main Points Raised

  • One participant requests assistance in finding the activation energy of adsorption and the corresponding rate constant, expressing confusion about the process.
  • Another participant seeks clarification on the specific parameters needed to calculate the activation energy, mentioning the equation for the diffusion coefficient and the known variables.
  • There is a suggestion that the topic may not relate to nuclear or particle physics, prompting a request to move the discussion to a more appropriate forum.
  • A participant confirms the focus on the adsorption of SDS on solid particles with polymers, such as Al and TiO2, clarifying the context of the inquiry.
  • A later reply provides a link to a resource that may help clarify the concept of activation energy, which the original poster finds helpful in resolving their confusion.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the methods to determine activation energy, as the discussion includes various perspectives and clarifications without a definitive resolution.

Contextual Notes

Participants express uncertainty regarding the calculation of activation energy and its dependence on specific parameters, with references to methods that may not apply to their context.

Who May Find This Useful

Researchers and students interested in adsorption processes, diffusion coefficients, and activation energy calculations in chemical and materials science contexts may find this discussion relevant.

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

i am confused ...please help me out?

thanks
 
Physics news on Phys.org
Please specify
 
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
 
thanks
i got it.

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