Which outcome occurs in an industrial ammonia synthesis reactor operating at high pressure when the iron catalyst becomes fouled by sulfur compounds?

A)Decreasing the equilibrium reaction yield

B)Increasing reactor temperature uncontrollably

C)Increasing the reactant's activation energy

D)Decreasing the reaction rate significantly✓

💡 Explanation

The reaction rate decreases because catalyst poisoning occurs, specifically sulfur compounds blocking active sites, thus inhibiting reactant binding; therefore the rate decreases rather than a change in the thermodynamics equilibrium because of the catalyst function.
