Answer to Question #235542 in Chemistry for Ajena

Question

A new law requires a method for evaluating whether automobiles are emitting too much carbon monoxide

Answer 1

This is quantitative analysis. You measure the exhaust emissions from many vehicles over many scenarios, such as idling, accelerating and normal driving, and then determine if any CO is allowed for a brief period or not. The figures do not lie, and can be used to determine compliance with whatever the legislators have nominated.
