Question

$Assertion:$ Nitrogen and Oxygen are the main components in the atmosphere but these do not react to form oxides of nitrogen.
$Reason:$ The reaction between nitrogen and oxygen requires high temperature.

• A. Both assertion and reason are correct, and the reason is the correct explanation for the assertion.
• B. Both assertion and reason are correct, and the reason is not the correct explanation for the assertion.
• C. The assertion is incorrect, but the reason is correct.
• D. Both the assertion and reason are incorrect.

Answer 1

The correct option is A Both assertion and reason are correct, and the reason is the correct explanation for the assertion.

Assertion is true as we know that nitrogen being highly stable does not react with oxygen in atmosphere.
The reaction of nitrogen with oxygen takes place at very high temperature, i.e., nearly 2000 $K$. This makes the reason also correct and the correct explanation for assertion.
