As per Braun's principle, yield of Ammonia will be more in Haber's process under

As per Braun's principle, yield of Ammonia will be more in Haber's process under conditions \( \boldsymbol{L}=\operatorname{Low} ; \boldsymbol{H}=\operatorname{high} ; \boldsymbol{T}=\operatorname{Temp} ; \boldsymbol{P}= \) Pressure)

  • A. \( L T ; L P \)
  • B. \( L T ; H P \)
  • C. \( H T ; H P \)
  • D. \( H T ; L P \)

Step-by-step solution

Braun's principle (Le Chatelier's principle) states that a system at equilibrium will shift to counteract changes. The Haber process is exothermic, so low temperature shifts equilibrium toward ammonia. Also, the reaction reduces the number of gas molecules (4 to 2), so high pressure favors product formation. Thus, low temperature and high pressure maximize yield.
