← ScienceWhich consequence occurs when insufficient activation energy impacts catalytic converters?
A)Increased uncombusted hydrocarbon emissions✓
B)Catalyst surface area rapidly decreases
C)Higher carbon dioxide formation
D)Reduced mechanical engine knocking
💡 Explanation
Insufficient activation energy hinders the redox reactions, whose mechanism dictates complete hydrocarbon combustion; because of reduced reaction rates within converters, polluting hydrocarbons cannot fully react; therefore emissions increase, rather than decreasing carbon dioxide.
