The answer to this question is option B. (I observed that butterflies prefer the yellow flowers.) The others are simply just opinions. Give me brainliest please :)
Answer:
The yield of hydrogen decreases
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.
