The correct condition for physical adsorption is
- A High \(T\) and high \(p\)
- B High \(T\) and low \(p\)
- C Low \(T\) and high \(p\)
- D \(T\) and \(p\) do not affect
Answer & Solution
Correct Answer
(C) Low \(T\) and high \(p\)
Step-by-step Solution
Detailed explanation
Physical adsorption is an exothermic process, which can be represented by the equilibrium: Adsorbate + Adsorbent \(\rightleftharpoons\) Adsorbed state + Heat. According to Le Chatelier principle, for an exothermic process, a decrease in temperature favors the forward reaction,…
