Hello,
We work on CO2 adsorption on active carbon and we find experimentally that this adsorption is physisorption. Next we try to fit the pseudo-first order that should work for physisorption but it did'nt work. So we try to fit the pseudo-second order and it works but usually pseudo-second order works for chemisorption. So why pseudo-second order works and pseudo-first order didn't ?
Thank you for your answer !
