Assertion: Copper metal gets readily corroded in an acidic aqueous solution.
Reason: Free energy change for this process is positive.
(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.
(d) If both the Assertion and Reason are incorrect.
Explanation:
Copper lies below hydrogen in electrochemical series so it cannot displace H2 from dilute acids. Hence it is not easily corroded in acidic solutions. Further, corrosion is a spontaneous process for which free energy change must be negative.
