← ScienceWhich outcome occurs when exhaust flow bypasses a catalyst?
A)Increased nitrogen oxide emissions✓
B)Decreased particulate matter production
C)Reduced fuel efficiency occurs
D)Elevated hydrocarbon combustion efficiency
💡 Explanation
Increased nitrogen oxide emission results, because the catalytic converter facilitates reactions via surface adsorption, specifically redox, and therefore the bypass prevents conversion rather than decreasing particulate emissions. Alternate pathways and fuel efficiency are negligibly affected.
