1.	Three ions sheets have been coated separately with three metals (A,B and C) whose standard electrode potentials are given below: `{:("Metal",A,B,C,"Iron"),(E_("value")^(@),-0.46,-0.66V,-0.20V,-0.44V):}` Identify in which case rusting will take place faster when coating is damaged.
Answer» Comparing oxidation potential of iron with those of metals A,B and C, iron has higher oxidation potential than C only. Hence, when coating of C is broken, rusting will become faster.
