Web18 Nov 2024 · What are the conditions used in the Haber process? The conditions used in the Haber process are: 200 atmospheres pressure • 450 °C • iron catalyst. Use the equation and your knowledge of reversible reactions to explain why these conditions are used in … WebThe temperature used – around 450\degree \text {C} – is chosen to give the best yield possible. In a similar way, a compromise pressure is used in the reaction. The equilibrium will be shifted to the forward reaction by increasing the pressure. This is the side of the reaction that has the fewest moles of gas and so is the lowest pressure.
