Question

Which of the following can adsorb larger volume of hydrogen gas?

• A. Finely divided platinum
• B. Colloidal solution of palladium
• C. Small pieces of palladium
• D. A single metal surface of platinum

Hint:

Greater surface area leads to higher adsorption of gases.

Answer 1

The Correct Option is B

Step 1: Understanding adsorption. 
- Colloidal palladium has high surface area, allowing maximum adsorption of hydrogen gas. 
Step 2: Selecting the correct option. 
Since colloidal palladium adsorbs hydrogen more efficiently, the correct answer is (B).
