JEE MAIN - Chemistry (2003 - No. 32)
Standard reduction electrode potentials of three metals A,B&C are respectively +0.5 V, -3.0 V & -1.2 V. The
reducing, powers of these metals are
A > B > C
C > B > A
A > C > B
B > C > A
Explicação
$$\matrix{
A & B & C \cr
{ + 0.5C} & { - 3.0V} & { - 1.2V} \cr
} $$
NOTE : The higher the negative value of reduction potential, the more is the reducing power.
Hence $$B > C > A.$$
