Assertion: Galvanised iron does not rust.
Reason: Zinc has a more negative electrode potential than iron.
(a) If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.
(b) If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.
(c) If the Assertion is correct but Reason is incorrect.
(d) If both the Assertion and Reason are incorrect.
(e) If the Assertion is incorrect but the Reason is correct.
(a) If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.
Explanation:
Galvanised iron does not rust easily because zinc (which is present in the form of coating) has more negative electrode potential (–0.76 V) than iron (– 0.41 V) i.e., Zn is less reactive than Fe.
