Vedclass · Answer

(A) The reactivity of metals with water depends on their position in the electrochemical series.$K$ and $Na$ are highly reactive and react vigorously with cold water.$Pt$ is a noble metal and does not react with water or steam.$Fe$ (Iron) is moderately reactive; it does not react with cold water but reacts with steam at high temperatures to form iron oxide and release $H_2$ gas according to the reaction:$3Fe(s) + 4H_2O(g) \rightarrow Fe_3O_4(s) + 4H_2(g)$.
