Answer:

O Chlorine is more reactive than bromine.

Explanation:

From this experiment we can conclude that chlorine is more reactive than bromine and it is the reason why the reaction is able to proceed.

  • The reaction is a single displacement reaction in which the position of an element in the activity series is very important.
  • Since chlorine is more electronegative and highly reactive when compared to bromine, it will displace bromine from the solution of potassium bromide.
  • So, we have product of potassium chloride and the bromide.
