There iron sheets have been coated separately with three metals (A,B and C ) whose standard electrode potentials are given below.
`{:("Metal"," "A," "B," "C," "Iron),(,-0.46" V",-0.66" V",-0.20" V",-0.44" V"):}`
Identify in which case rusting will take place faster when coating is damaged.

Text Solution

Verified by Experts

Rusting of iron will occur faster when coated with metal C because it is placed above iron in the activity series. Iron will take part in redox reaction and not the metal C.
