Mass Transfer Though, theoretically the adsorption & desorption isotherms is expected to coincide but sometimes at least a part of the isotherms does not coincide and this phenomenon is known as adsorption hysterisis. In such cases, the desorption equilibrium pressure is __________ that obtained for adsorption. Same as Higher than Either same or higher than Lower than Same as Higher than Either same or higher than Lower than ANSWER DOWNLOAD EXAMIANS APP
