Question
In which of the following cases does adsorption occur more readily?a.Low temperature and high pressureb.High temperature and high pressurec.Low temperature and low pressured.High temperature and low pressure
Solution
Adsorption occurs more readily in the case of low temperature and high pressure. This is because adsorption is an exothermic process, meaning it releases heat. Therefore, lower temperatures are more favorable for adsorption. Additionally, higher pressure increases the number of molecules in the gas phase that can interact with the adsorbent surface, thus increasing the rate of adsorption. So, the correct answer is a. Low temperature and high pressure.
