Question

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

Answer 1

Correct Answer - 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.
