Assertion (A) van der Waals' forces are reponsible for chemisorptions.Reason (R) High temperature is favourable for chemisorptions.
The correct answer is
- A (A) is false, but (R) is true
- B Both \((A)\) and \((R)\) are correct and \((R)\) is the correct explanation of \(\mathrm{A}\)
- C Both \((A)\) and \((R)\) are correct and \((R)\) is not the correct explanation of (A)
- D (A) is true, but (R) is false
Answer & Solution
Correct Answer
(A) (A) is false, but (R) is true
Step-by-step Solution
Detailed explanation
van der Waals' forces are not responsible for chemisorptions. These forces are involved in physisorption. For chemisorptions, high temperature is favourable. It increases with increase of temperature.
