___
Answer Key:
1. Key components include hydrogen and nitrogen. (0:40)
2. They were awarded Nobel Prizes for their contributions to large-scale industrial processes. (0:33)
3. A low temperature is favored for the reaction's favorability, but a compromise temperature of 400-450°C ensures a
reasonable reaction rate. (2:40)
4. Le Chatelier's principle states that increasing pressure favors the side with fewer moles, which in this case is
ammonia production. (1:51)
5. Recycling prevents waste of reactants and maximizes efficiency in the process. (3:18)
