What is the thermodynamic basis for the decrease in physical adsorption with increasing temperature?

Options

  1. AIncrease in Gibbs energy
  2. BDecrease in Gibbs energy
  3. CIncrease in entropy
  4. DDecrease in entropy

Correct answer

D. Decrease in entropy

Step-by-step solution

The paragraph mentions that physical adsorption decreases with increasing temperature, which aligns with Le-Chatelier’s principle, where an exothermic process decreases with an increase in temperature, leading to a decrease in entropy.
