Question
When the temperature is lowered and pressure is raised, the adsorption of a gas on a solida.Increasesb.Remains unaffectedc.Decreasesd.Decreases first then increases
Solution
The adsorption of a gas on a solid generally increases when the temperature is lowered and pressure is raised. This is because adsorption is an exothermic process, meaning it releases heat. Therefore, lowering the temperature favors the process. Similarly, increasing the pressure also favors adsorption as it increases the concentration of the gas, making it more likely for the gas molecules to interact with the solid surface. So, the correct answer is a. Increases.
