High pressure of 200 atm in Haber process is used for:
Correct answer: A. Better yield
- A. Better yield
- B. Lower yeild
- C. Lower rate
- D. Cost change
Explanation
Increasing the pressure increases the yield in Haber's process because the number of moles of products is less than the number of moles of reactants. Increasing the pressure shifts the equilibrium to the right.

About Thermochemistry and Energetics of Chemical Reactions
Thermochemistry measures energy changes in chemical reactions and distinguishes exothermic from endothermic processes. Work covers systems, surroundings and state functions, internal energy, the first law of thermodynamics, enthalpy and Hess's law, including the sign conventions used when heat enters or leaves a system.
