Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Concept
Adsorption from solution.
Step 2: Meaning
Factors influencing solution-phase adsorption.
Step 3: Analysis
Adsorption is exothermic, so it decreases with temperature (I). Higher concentration leads to more adsorption (II). It depends on the chemical nature of both components (III).
Step 4: Conclusion
All statements I, II, and III are correct.
Final Answer: (A)
