Question

2 metal p and q p is less reactive than q suggest activity to arrange these metals in their decreasing reactivity

Answer 1

activity-
take salt solution of metal p and metal q in it.since q is more reactive than p so displacement reaction will take place. the metal q will displace p from its salt solution.
Salt solution of metal P + metal Q --> salt solution of metal q + metal p
thus reactivity orders of metals :
Q > P
