Question

Favourable conditions for manufacture of ammonia by the reaction, N2 +3H2 leftharpoons 2NH3; Δ H=-21.9 kcal are (A) low temperature, low pressure and catalyst (B) low temperature, high pressure and catalyst (C) high temperature, low pressure and catalyst (D) high temperature, high pressure and catalyst

Tardigrade Admin · Accepted Answer

The formation of ammonia is favoured by high pressure which would shift the reaction in the forward direction. The reaction shifts in forward direction at low temperature and more product formation occurs Fe acts as a positive catalyst and also shifts the reaction in forward reaction

Q. Favourable conditions for manufacture of ammonia by the reaction, N2​+3H2​⇌2NH3​; ΔH=−21.9kcal are

low temperature, low pressure and catalyst

low temperature, high pressure and catalyst

high temperature, low pressure and catalyst

high temperature, high pressure and catalyst

The formation of ammonia is favoured by high pressure which would shift the reaction in the forward direction. The reaction shifts in forward direction at low temperature and more product formation occurs Fe acts as a positive catalyst and also shifts the reaction in forward reaction
