Assertion (A) : Cu gets readily corroded...

Assertion `(A) : Cu` gets readily corroded in acidic aqueous solution.
Reason `(R) :` Free energy of the process is positive.

A

If both `(A)` and `(R)` are correct, and `(R)` is the correct explanation of `(A)`.

B

If both `(A)` and `(R)` are correct, but `(R)` is not the correct explanation of `(A)`.

C

If `(A)` is correct, but `(R)` is incorrect.

D

If both `(A)` and `(R)` are incorrect.

Text Solution

Verified by Experts

The correct Answer is:
e
Both `(A)` and `(R)` are incorrect.
Correct `(A):` Pure `Cu` does not corrode even in the most corrosive environment.
Correct `(R):` Corrosion is a spontaneous process for which `DeltaG` must be `-ve`.
