For the reaction in equilibrium N ₂( ~g )+3 H ₂( ~g ) 2 NH ₃( ~g ), H =- Q Reaction is favoured in forward direction by:

Options

  1. Ause of catalyst
  2. Bdecreasing concentration of N ₂
  3. Clow pressure, high temperature and high concentration of ammonia
  4. Dhigh pressure, low temperature and higher concentration of H ₂

Correct answer

D. high pressure, low temperature and higher concentration of H ₂

Step-by-step solution

N ₂( ~g )+3 H ₂( ~g ) 2 NH ₃( ~g ), H =- Q According to Le Chatelier's principle. - Exothermic reactions are favoured at low temperature. - Increase in pressure shifts the reaction in direction having lesser number of moles. Hence, the given reaction shifts forward on increasing pressure. - Increasing the concentration of reactants shifts the reaction in forward direction. So high concentration of H ₂ shifts reaction in forward direction.
