Solution Summary
The following posting explains how the given factors change the direction of the exothermic reaction. The solution is detailed and has a '5/5' rating.
Solution Preview
Le Chatelier's principle says that a system adjusts to minimize stress. Consequently, the equilibrium shifts such that whatever is added is removed.
First take a look the concentration changes:
The concentration can be changed by adding or removing a substance. If added, the equilibrium shifts to remove the substance. If removed, the equilibrium shifts to replace it.
(b) removing Br2: because the reactant is removed, the equilibrium shifts to the left to replace it. so it does not work ...
