1. A petroleum refinery is breaking down large hydrocarbon molecules into smaller, more valuable ones (like gasoline components) using high temperatures and catalysts. What process are they performing?

2. Which polymer is produced using Ziegler-Natta catalysts?

3. In the contact process, which catalyst is used to convert SO₂ to SO₃?

4. An industrial chemist is optimizing a process to convert vegetable oils into solid fats by adding hydrogen across double bonds in the presence of a catalyst. What reaction is this?

5. What is the primary raw material for the production of most plastics?

6. A manufacturing plant needs to purify a liquid mixture containing components with significantly different boiling points. They heat the mixture to vaporize the more volatile component, then condense it. What separation technique are they using?

7. A company is producing ethanol for use as a biofuel from corn. This process involves using microorganisms to convert sugars into alcohol and carbon dioxide. What biological industrial process is this?

8. Green chemistry promotes replacing hazardous solvents with which of the following?

9. Which industrial process is used to produce chlorine gas and sodium hydroxide from brine (saltwater) using electrolysis?

10. A company is developing a new fertilizer and needs a large supply of phosphoric acid. Which industrial process, often involving the reaction of phosphate rock with sulfuric acid, is used for its production?

11. Which industrial process is used to separate crude oil into different fractions (like gasoline, diesel, kerosene) based on their boiling points?

12. Which chemical is primarily used in the Haber process for ammonia production?

13. What is the main environmental concern associated with the sulfuric acid industry?

14. Which industrial process is used to produce sodium carbonate (soda ash) from sodium chloride, ammonia, and carbon dioxide?

15. An industrial process requires a continuous flow of reactants through a reactor where they are converted into products, allowing for large-scale, uninterrupted production. What type of reactor is typically used for this?

16. Which of the following is a common industrial method for producing hydrogen gas?

17. A chemical engineer is designing a reactor to produce a large quantity of a specific polymer. They are selecting a process where individual monomer units are linked together repeatedly to form long chains. What type of industrial process are they utilizing?
