Question

N₂ + 3H₂ ⇋ 2NH₃ + Heat

The Le Chatelier's principle suggests that are required to drive the reaction to the right and thus form NH₃. 

1. high pressure and low temperature
2. low pressure and low temperature
3. high pressure and high temperature
4. low pressure and high temperature

Answer 1

Correct Answer - Option 1 : high pressure and low temperature

The correct answer is high pressure and low temperature.

• This equation is an example of Equilibrium.
• Equilibrium is a condition that occurs when a chemical reaction is reversible, and the forward and reverse reactions occur simultaneously, at the same rate.
• Le Chatlier's Principle- "if a chemical system at equilibrium experiences a change in concentration, temperature or total pressure, the equilibrium will shift in order to minimize that change" 
• Any decrease in nitrogen or hydrogen pulls the reaction towards the left side.
• Any decrease in ammonia or temperature pulls the reaction towards the right side.
