Question

Assertion: Motor vehicles equipped with catalytic converter should use unleaded petrol.

Reason: The catalyst used in the catalytic converter gets inactivated by the lead in the petrol.

Options

• Both assertion and reason are true but reason is not the correct explanation of assertion.

• Assertion is true but reason is false.

• Both assertion and reason are false.

Answer 1

Both assertion and reason are true and reason is the correct explanation of assertion.

Explanation:

Motor vehicles equipped with catalytic converters should use unleaded petrol because the lead in petrol inactivates the catalyst. The catalytic converter uses expensive metals like platinum, palladium, and rhodium that facilitate the conversion of harmful gases into less harmful ones. Lead in petrol deposits on the catalyst and deactivates it, reducing its efficiency in controlling pollution.
