Solution

The correct option is C no
When anode and cathode are not connected, then the potential difference is maxium between them.
Current is zero in an open curcuit as the circuit is not complete.

Q. Assertion :EMF of the cell is the potential difference between the electrode potentials of the cathode and anode when no current is drawn through the cell. Reason: Anode is kept on the right side and cathode on the left side while representing the galvanic cell.

Q. Consider the following relations for emf of an electrochemical cell :

(i) EMF of cell = (Oxidation potential of anode) - (Reduction potential of cathode)
(ii) EMF of cell = (Oxidation potential of anode) + (Reduction potential of cathode)
(iii) EMF of cell = (Reduction potential of anode) + (Reduction potential of cathode)
(iv) EMF of cell = (Oxidation potential of anode) - (Oxidation potential of cathode)

Which of the above relation(s) is correct?

Q. Consider the following relations for emf of an electrochemical cell:

(i) EMF of cell = (Oxidation potential of anode) - (Reduction potential of cathode) (ii) EMF of cell = (Oxidation potential of anode) + (Reduction potential of cathode) (iii)) EMF of cell = (Reductional potential of anode) + (Reduction potential of cathode) (i v)) EMF of cell = (Oxidation potential of anode) - (Oxidation potential of cathode)

Q. In an electrochemical cell, anode and cathode are__________.

Q. Assertion :Anode is the electrode at which oxidation occurs and cathode is the electrode at which reduction occurs. Reason: Anode and cathode in electrochemical cells and electrolytic cells have opposite polarity.
