Question

A typical example of an exothermic reversible reaction conducted at high pressures in industry is

• A. dehydration of ethanol,
• B. methanol synthesis,
• C. reformation of ethane,
• D. polymerisation of ethylene,

Hint:

Exothermic reactions like methanol synthesis are commonly carried out at high pressures to shift the equilibrium toward product formation.

Answer 1

The Correct Option is B

- Methanol synthesis is an exothermic reversible reaction that typically occurs at high pressures in the presence of a catalyst.
- Dehydration of ethanol is an example of a reaction, but not necessarily a reversible exothermic reaction under high pressure. 
- Reformation of ethane is generally not a high-pressure process. 
- Polymerisation of ethylene is an exothermic reaction but doesn't necessarily take place at high pressures. 
Conclusion: 
Methanol synthesis is the correct example of an exothermic reversible reaction conducted at high pressures in industry.
