Step 1
Which equation best represents catalytic cracking of a petroleum fraction?
Answer
Catalytic cracking is a process used in the petrochemical industry to break down larger hydrocarbon molecules into smaller, more useful ones. Option (C) is the correct representation of this process:
This equation shows the conversion of a heavier liquid hydrocarbon into a mixture of lighter gaseous products, which is characteristic of catalytic cracking.
