Why does chlorine displace bromine from potassium bromide solution?

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.

Why bromine does not react with aqueous potassium chloride?
Chlorine is more reactive than bromine thus bromine is unable to displace chlorine to form potassium bromide.
What is the name of the reaction of potassium bromide with chlorine?
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
Will chlorine and potassium bromide react?
yes yes
What are the observations when chlorine reacts with potassium bromide?
Red coloured bromine is formed. Bromides are displaced by chlorine.
Why does the color of aqueous potassium bromide change when chlorine gas is bubbled into it?
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-
Which would be likely to displace a bromide ion from solution?
chlorine
Would you expect iodine to displace bromine form a solution of potassium bromide?
No. However, bromine would displace iodine in potassium iodide.
Why bromine does not react with aqueous potassium chloride?
Chlorine is more reactive than bromine thus bromine is unable to displace chlorine to form potassium bromide.
What would be observed if chlorine water was added to a dilute solution of sodium bromide?
Chlorine will displace bromine from NaBr
What is the name of the reaction of potassium bromide with chlorine?
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
What color change occurs when chlorine gas is passed through a solution of potassium bromide?
it goes from colourless to red/brown
Will chlorine and potassium bromide react?
yes yes
What is the equation for the reaction with chlorine and potassium bromide?
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
Why chlorine displaces bromine from potassium bromide?
Chlorine is a stronger oxidizing agent than bromine.
What is the colour of potassium bromide solution?
If pure, colorless.
What is the formula for a Molecular chlorine is added to a solution of sodium bromide?
molecular chlorine is added to a solution of sodium bromide fine the balance equation and the net ionic equation
What are the observations when chlorine reacts with potassium bromide?
Red coloured bromine is formed. Bromides are displaced by chlorine.
