In the catalytic cracking of long-chain hydrocarbons, such as decane, the reactant is heated to high temperatures to break it down into smaller, more useful alkanes and alkenes. This decomposition reaction is endothermic.
On the axes provided, draw a reaction profile for this endothermic reaction.
Your profile should clearly show and label:
