← ScienceWhich outcome occurs when Arrhenius constant is significantly lower than expected in catalytic reactor?
A)Reaction rate being significantly slower✓
B)Equilibrium shifts towards product formation
C)Apparent activation energy reduces
D)Catalyst surface area increases rapidly
💡 Explanation
When the Arrhenius constant is lower, the number of successful collisions decreases, lowering pre-exponential factor because temperature sensitivity, leading to a slower reaction rate. Therefore a lower reaction rate is observed, rather than changed equilibrium, activation energy reduction or catalyst area increase which are indirectly affected by other parameters.
