Which inefficiency arises when insufficient tungsten coverage results from catalyst poisoning in an ammonia synthesis reactor?

A)Increased bypass of unreacted substances
B)Elevated activation energy requirement
C)Decreased optimal particle size
D)Accelerated catalyst surface area decline

💡 Explanation

Poisoning reduces available active W sites, altering reactant adsorption and increasing reactant bypass of those sites; because of decreased catalysis the flow dynamics matter more, therefore unreacted substances pass through rather than lowering optimal particle size because reactions are limited to fewer sites.
