Question

what happens to the adsorption if the activation energy is increased??

Answer 1

Dear Student

Rate of adsorption will increase with the increase in activation energy and is given by -
R_adp = k^'p^x
where, k^' = rate constant; p = partial pressure; x = kinetic order

Now, if this equation is expressed in Arrhenius form, we obtain -
R_adp = A_exp (-E_a/RT) P^x
where, E_a = the activation energy for adsorption; A = pre-exponential frequency factor
