← ScienceWhich consequence results when the rate constant of a catalytic ammonia synthesis reactor decreases significantly?
A)Incomplete conversion of reactants✓
B)Excessive catalyst bed temperature
C)Runaway reaction from increased pressure
D)Formation of explosive byproducts
💡 Explanation
When the rate constant decreases, the reaction slows because the activation energy is effectively higher, leading to lower product formation at the same residence time, therefore incomplete conversion results, rather than higher temperatures, pressure increases, or explosive byproducts which require alternate reaction dynamics.
