Assertion `(A):` For four half`-` cell reactions involving different number of electrons,
`E_(4)=E_(1)+E_(2)+E_(3)`
Reason `(R): DeltaG_(4)=DeltaG_(1)+DeltaG_(2)+DeltaG_(3)`

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

Text Solution

Verified by Experts

The correct Answer is:
D
`(A)` is incorrect since `EMFs` are neither additive nor subtractice.
`(R)` is correct but not the explanation of `(A)`. `(R)` is an independent statement and `DeltaG` are additive or subtrative.
