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

Options

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.

Answer

e

Explanation

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`.
