Discuss the effect of pressure and temperature on the adsorption of gases on solids.
Explanation The effect of temperature and pressure on the adsorption of gases on solids is: 1. The effect of pressure on adsorption of gases on solids is such that the adsorption and pressure are directly proportional to each other i.e. the adsorption increases when the pressure increases. 2. According to Le-Chatelier’s principle, adsorption and temperature are inversely proportional to each other i.e. as the temperature increases, the magnitude of adsorption will decrease making adsorption an exothermic process. Final Answer In the process of adsorption of gases on a solid, pressure is directly proportional to the rate of adsorption and temperature in inversely proportional to the rate of absorption.
