In catalytic cracking process, olefins crack ______________ times faster than in thermal cracking process?
Correct answer: C. 1000-10000
- A. 100
- B. 200-300
- C. 1000-10000
- D. 10
Explanation
Catalysts strongly accelerate the cracking of olefins by providing a lower-energy reaction pathway, making their cracking rate roughly 1,000 to 10,000 times that in thermal cracking. This is why option c is the characteristic comparison.
