Assertion : (Ni)|(Ni^(2+))(1.0M)|| Au^(3...

Assertion : `(Ni)|(Ni^(2+))(1.0M)|| Au^(3+)(l.0M)|Au` for this cell emf is 1.75 V, if `E_(Au^(3+)//Au)^(@) =1.50` and `E_(Ni^(2+)) // Ni^(@)=0.25 V`
Reason: Emf of the cell =`E_(cathode)^(@)-E_(anode)^(@)`

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

D

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

Text Solution

Verified by Experts

The correct Answer is:
C
Potential difference is the difference between the electrode potential of the two electrodes of the cell when cell is under operation while emf is the potential difference generated by a cell when there is zero electron flow
