The Haber process uses an iron catalyst.
Statement 1: The catalyst increases the rate of both the forward reaction and the backward reaction.
Statement 2: The catalyst increases the equilibrium yield of ammonia.
Statement 3: The catalyst means that an acceptable rate is reached at a lower temperature, which gives a higher equilibrium yield.
