Why does physical adsorption occur readily at low temperatures, according to Le-Chatelier’s principle?
Options
- AIt is an endothermic process.
- BIt is an exothermic process.
- CIt is independent of temperature.
- DTemperature has no effect on adsorption.
Correct answer
B. It is an exothermic process.
Step-by-step solution
The paragraph states that since the adsorption process is exothermic, physical adsorption occurs readily at low temperatures.
