Question

Give three examples of application of Lee Chatelier's principle to chemical equilibria.

Answer 1

The examples of the application of Lee Chatelier's principles include:

1. Synthesis of ammonia: an increase in pressure favors the formation of products. The optimum pressure for maximum yield is approximately 200 atm.
2. Synthesis of sulfur trioxide: decrease in temperature favors forward reaction as the reaction is exothermic. The optimal temperature is 723 K for the reaction.
3. Ozone synthesis: increasing the temperature favors the formation of ozone as the reaction is endothermic.
