Question

• Assertion: Rusting of Iron is endothermic in nature.
• Reason: As the reaction is slow, the release of heat is barely evident.

विकल्प

• Both A and R are true, and R is the correct explanation of A.

• Both A and R are true, and R is not the correct explanation of A.

• A is true but R is false.

• A is false but R is true.

Answer 1

A is false but R is true.

Explanation:

The combination between iron and wet air that results in rust is an exothermic reaction that produces a lot of heat. This reaction is so gradual that the release of heat is barely noticeable.
