Question:
Identify the correct statements from the following:
I) In adsorption process, both enthalpy and entropy decrease.
II) In general, physisorption is an irreversible process.
III) The catalyst used in the decomposition of potassium chlorate is manganese dioxide.

II) In general, physisorption is an irreversible process.
III) The catalyst used in the decomposition of potassium chlorate is manganese dioxide.
Show Hint
Catalysts do not alter equilibrium, only the rate. Physisorption is generally reversible.

Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
In adsorption, the process is exothermic and leads to decreased entropy (randomness).
Manganese dioxide is used as catalyst in decomposition of KClO$_3$. However, physisorption is usually reversible, not irreversible.
