Why is high pressure required in the haber process?

If the pressure is increased, the equilibrium position moves in the direction of the fewest molecules of gas. This means it moves to the right in the Haber process. ... Stronger equipment is needed, and more energy is needed to compress the gases. So a compromise pressure of 200 atmospheres is chosen.

Explanation:

- "the choice that is not an indicator of a chemical change is "state of matter changes". more common than not, chemical reactions produce energy in the form of light or heat. along with energy, they also produce a new substance called the product that could be in any state of matter (solid, gas, or liquid)."

c. heat could easily travel through the molecules in the air and escape/enter the flask. removing the air slows down the heat transfer.
