identify the reason a catalytic converter can fail when a catalyst becomes coated by a substance such as lead from leaded fuel. a. contamination b. overheating c. old age d. wear
Answer
Brief Explanations:
When a catalyst in a catalytic converter is coated by a substance like lead (a foreign substance), this is a case of contamination. Overheating would involve high - temperature damage, old age is a general wear - out over long periods not specifically related to coating, and wear is more about physical abrasion rather than coating by an external substance.
Answer:
A. Contamination
