|---|---|
| What is Cracking? Why is it Performed? | -This is simply the Process of turning Long Alkane Molecules into Smaller Alkanes, and Alkenes Molecules -This is because Smaller Alkanes and Alkenes can be more Useful, and also have a much Higher Demand for it [Diesel < Petrol] |
| How does Cracking happen? | -Since its Thermal Decomposition, [Breaks down when its Heated] you need Heat to break down the Covalent Bond that holds the Long Alkane Molecule up -If its Vaporised [The Hydrocarbon that is] then its Passed over a Powdered Catalyst [Aluminium Oxide] with 400-700 Degrees and 70 ATM |
| Give an Example with the Cracking of Paraffin. Make Ethene one of the Products | Paraffin --[Aluminium Oxide]--> Octane [Alkane] + Ethene [Alkene] C₁₀H₂₂ --> C₈H₁₈ + C₂H₄ |
