Haber’s process

The video tutorial explains the Haber process, which involves forming ammonia from nitrogen and hydrogen. It discusses how the yield of ammonia can be increased by reducing its concentration, such as by liquefying the gas. The tutorial also covers the decomposition reaction of calcium carbonate to form calcium oxide and carbon dioxide, highlighting that the yield of calcium oxide can be increased by removing the carbon dioxide gas.

What is the primary method to increase the yield of ammonia in the Haber process?

• Increasing the temperature

• Decreasing the pressure

• Liquefying the ammonia gas

• Adding more nitrogen

What is the main product formed from the decomposition of calcium carbonate?

• Calcium nitrate

• Calcium chloride

• Calcium oxide

• Calcium sulfate

How can the yield of calcium oxide be increased in the decomposition reaction of calcium carbonate?
