Ammonia is produced by the Haber process. The equation is shown. N2 (g) + 3H2 (g) ⇔ 2NH3 (g)

The forward reaction is exothermic.

Which statement is correct?

Increasing pressure decreases the yield of ammonia, but speeds up the reaction.

Increasing temperature decreases the yield of ammonia, but speeds up the reaction.

Increasing the concentration of hydrogen and nitrogen results in a lower yield of ammonia.

Increasing the temperature increases the yield of ammonia and speeds up the reaction.
