Question

Mark the incorrect statement.

• A. The limiting equivalent conductance for weak electrolytes can be computed with the help of Kohlrausch’s law.
• B. EMF of a cell is the difference in the reduction potential of cathode and anode.
• C. For cell reaction to occur spontaneulsy the EMF of the cell should be negative
• D. Fluorine is the strongest oxidizing agent as its reducing potentials is very high.

Answer 1

Answer: (C)

For cell reaction to occur spontaneulsy the EMF of the cell should be negative

Answer 2

$Eº_{cell}$ should be positive for a spontaneous reaction as $\Delta Gº = - nFEº_{cell}$
