Fundamentally, because this reaction reduces the Gibbs free energy of the reactants when they are converted to products. Chlorine atoms have substantially greater electronegativity than bromine atoms, while chloride and bromide ions both have about the same, very low, electronegativity. Therefore, chemical potential energy is reduced by removing an electron from each bromide ion to form a bromine atom and transferring the electron so removed to chlorine atoms to form chloride ions instead of bromide ions.
Chlorine displaces bromine as it is more reactive, and it creates sodium chloride aqueous and bromine aqueous.
This is a halogen single replacement reaction, in which the more active chlorine will take the place of the bromine in the potassium bromide. 2KBr + Cl2 --> 2KCl + Br2
yes yes
Red coloured bromine is formed. Bromides are displaced by chlorine.
Chlorine is a stronger oxidizer than elemental Bromine. So, when yellowish chlorine gas is bubbled through the Bromide solution, a red colour is formed which is Bromine. Chlorine oxidizes Bromide ions to elemental Bromine while itself is reduced to Chloride ions. So, the total reaction is: Cl2 + Br- ----> Br2 + Cl-
Chlorine is a stronger oxidizing agent than bromine.

it goes from colourless to red/brown
yes yes
chlorine plus potassium bromide gives bromine plus potassium chloride. Here is the symbol equation, but remember that the numbers AFTER the symbols should be subscripts. Cl2 + 2KBr = Br2 + 2KCl
If pure, colorless.
molecular chlorine is added to a solution of sodium bromide fine the balance equation and the net ionic equation

Chlorine is more reactive than bromine thus bromine is unable to displace chlorine to form potassium bromide.
