Question

Powdered substances are more effective adsorbents than their crystalline forms because ____________.

Options

• surface area increases

• all of these

• pressure increases

• temperature increases

Answer 1

Powdered substances are more effective adsorbents than their crystalline forms because surface area increases.

Explanation:

With an increase in adsorbent surface area, both physisorption and chemisorption rise. The adsorbent's surface area can be enhanced by powdering it.
