Question

                                blue + 4 Br- (aq) <--> green +   6H2O(l)

When the temperature of a system at equilibrium is increased,the system reacts as if we added a reactant to an endothermicreaction or a product to an exothermic reaction. Theequilibrium shifts in the direction that consumes the excessreactant (or product), namely heat.

As we lower the temperature, the equilibrium shifts to the sidethat produces heat. Thus, cooling an endothermic reactionshifts the equilibrium to the left. Cooling an exothermicreaction shifts the equilibrium to the right.

Answer:

Because the green equilibrium solution (products) in an ice bathshifted to the blue equilibrium solution (reactants), this meansthe reverse reaction is endothermic because cooling endothermicreactions causes the equilibrium to shift left. Therefore, theforward reaction is exothermic because this is an oppositeeffect.

Explanation / Answer

The color indication deals with heat and changes according tothe color scheme ROYGBIV red orange yellow green blue indigo violetas the temperature decreases the molecules cool yieding in aslowing in the reaction changing the indicator togreen instead ofthe blue which is a warmer color in terms of intensity ofheat. This might help in your understanding so that you can solvethe problem
