Question

Assertion: The rate constant does not depend upon the initial concentration of reactants.

Reason: The rate of reaction in the beginning cannot be measured accurately.

Options

• 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 Assertion is CORRECT but Reason is INCORRECT.

Explanation:

Assertion is correct because the rate constant depends only on temperature, not on initial concentration. Reason is incorrect, as the difficulty in measuring the initial rate has no connection with the definition of rate constant.
