Step 1
Identify the correct equation for catalytic cracking
Answer
The correct equation representing catalytic cracking of a petroleum fraction is option (C): .
Catalytic cracking involves breaking down a larger hydrocarbon molecule into smaller, more valuable hydrocarbons. In option (C), is broken down into smaller alkanes, which fits the definition of catalytic cracking.
