During the adsorption of krypton on activated charcoal at low temperature
- A \(\Delta H < 0\) and \(\Delta S < 0\)
- B \(\Delta H>0\) and \(\Delta S < 0\)
- C \(\Delta H>0\) and \(\Delta S>0\)
- D \(\Delta H < 0\) and \(\Delta S>0\)
Answer & Solution
Correct Answer
(A) \(\Delta H < 0\) and \(\Delta S < 0\)
Step-by-step Solution
Detailed explanation
During adsorption, heat is liberated hence \(\Delta H\) is negative (less than zero) and entropy decreases.
