Question

Assertion: Finely divided solid reactants react much faster as compared to massive reactants.

Reason: Finely divided solid reactants possess a larger surface area.

विकल्प

• If both Assertion and Reason are CORRECT and Reason is the CORRECT explanation of the Assertion.

• If both Assertion and Reason are CORRECT but Reason is not the CORRECT explanation of the Assertion.

• If Assertion is CORRECT but Reason is INCORRECT.

• If Assertion is INCORRECT but Reason is CORRECT.

Answer 1

If both Assertion and Reason are CORRECT and Reason is the CORRECT explanation of the Assertion.

Explanation:

Finely divided solids have a larger surface area, which increases the number of collisions with reactant particles. This leads to a faster reaction rate compared to bulky solids. Hence, the reason correctly explains the assertion.
