← ScienceWhich mechanism reduces energy consumption when a catalytic converter reaches operating temperature?
A)Decreased exhaust back pressure
B)Enhanced reaction rate kinetics✓
C)Increased oxygen storage capacity
D)Improved air-fuel mixture homogeneity
💡 Explanation
When a catalytic converter reaches operating temperature, enhanced reaction rate kinetics occurs because the activation energy for pollutant oxidation/reduction is lowered, leading to more efficient conversion. Therefore, energy consumption is reduced, rather than back pressure, storage, or homogeneity which are secondary effects.
