The effect of temperature on the adsorption of a gas on a solid surface can be explained using two well-known adsorption isotherms: the Langmuir isotherm and the Freundlich isotherm. However, to provide a general understanding, we can discuss the role of temperature in the adsorption process in terms of the adsorption type: physisorption and chemisorption.1. Physisorption: In physisorption, the adsorption of gas molecules on a solid surface occurs due to weak van der Waals forces. As the temperature increases, the kinetic energy of the gas molecules also increases, which weakens the attractive forces between the gas molecules and the solid surface. As a result, the adsorption capacity decreases with increasing temperature. This phenomenon is in accordance with Le Chatelier's principle, which states that a system in equilibrium will shift to counteract any changes in its conditions.2. Chemisorption: In chemisorption, the adsorption of gas molecules on a solid surface involves the formation of chemical bonds between the gas molecules and the surface. This process is usually temperature-dependent and can be either exothermic or endothermic. For exothermic chemisorption, increasing the temperature may weaken the chemical bonds, leading to a decrease in adsorption capacity. However, for endothermic chemisorption, increasing the temperature may provide the necessary energy for bond formation, resulting in an increase in adsorption capacity.In summary, the effect of temperature on the adsorption of a gas on a solid surface depends on the type of adsorption physisorption or chemisorption and the specific interactions between the gas molecules and the solid surface. Generally, physisorption decreases with increasing temperature, while chemisorption can either increase or decrease depending on the nature of the chemical bonds involved.
