Question

how does the reactivity series of metal help in predicting the relative activities of various metals

Answer 1

metals at top of reactivity series are more reactive like K, Na , Ca , Mg ,Al

metals at middle of reactivity series are moderately reactive like Zn ,Fe ,Sn


metals at lower position are least reactive and noble like Ag , Au etc

Answer 2

according to reactivity series we could conclude which metal is high reactive and low reactive By this we can conclude that which metal is more electropositive snd which is less electropositive . Which will help us in displacement reaction because in displacement reaction a high reactive metal displaces a low reactive metal
