In the Haber process, gaseous ammonia is produced on an industrial scale by combining nitrogen and hydrogen gases, according to this equation:
N2 (g) + 3H2 (g) = 2 NH3 (g)
The process is exothermic. Which of the following actions will shift the reaction in
the forward (product) direction?
Decrease the pressure of the reaction.
Increase the temperature of the reaction.
Reduce ammonia concentration by removing ammonia from the reaction
chamber.
Reduce hydrogen concentration by reducing the amount of hydrogen in the
reaction chamber.
