In the Haber process, what is the effect of increasing the pressure on the yield of ammonia?
The yield of ammonia increases.
The yield of ammonia decreases.
The yield remains unchanged.
The reaction stops.
Explanation
The Haber process involves the reaction: N₂(g) + 3H₂(g) ⇌ 2NH₃(g). Increasing the pressure favors the side with fewer moles of gas, which is the product (ammonia).
