Answer» Correct Answer - B Given examples are of non-metals . A non-metal having higher reduction potential replaces the other from its solution Thus `E_(RP_(D))^(@) gt E_(RP_(A))^(@) gt E_(RP_(B))^(@)` Hence only choice is (b) because `E_(OP_(B))^(@) gt E_(OP_(C))^(@)` as B replaces C from solution . |
