Question

what happens to the yield of hydrogen if the reaction is carried out at a higher pressure but at the same temperature​

Answer 1

The yield of hydrogen decreases

Step-by-step explanation:

The Haber process is exothermic. The equation of the Haber process is;

N2(g) + 3H2(g) --------> 2NH3(g) ΔH = -ve

Now, if we maintain a constant temperature, the number of volumes will affect the yield of products as follows;

The higher the pressure the lesser yield of hydrogen because the increase in pressure shifts the equilibrium position towards the right hand side.
