The Haber-Bosch process is used in industry to produce ammonia. Explain how the use of high temperature and pressure affects the rate of reaction.

According to collision theory: Increasing the temperature increases the average energy of the system. This means more molecules have enough energy to overcome the activation enthalpy when they collide, causing more collisions to be successful and hence leading to a faster reaction. Increasing the pressure increases the number of collisions between the molecules, meaning a higher likelihood for a successful collision.
