Question

Define reactivity series. Study the following reactions and arrange the metals A. B & D on
the basis of increasing reactivity.
A-BC — AC + B
D-AC no reaction
D-BC — DC + B

Answer 1

Answer:

In chemistry, a reactivity series is an empirical, calculated, and structurally analytical progression of a series of metals, arranged by their "reactivity" from highest to lowest.

in a displacement reaction a highly reactive element will displace the lower one

in 1st reac, i.e, A+BC -- AC + B

B is displaced by C

Thus C>B

in 3rd reac i.e, D+BC--DC+B

B is displaced by D

D>B

in 2nd one C can't displace D

so D>C

thus, D>C>B
