Solution Summary
This solution describes in 304 words Le Chatelier's principle and how this relates to each of the 4 possible answers by using them as case studies to demonstrate what would happen in the reaction. Finally, it answers the question of which addition/removal would cause the reaction to move left.
Solution Preview
The reaction we have is as follows:
NH4Cl<==> NH3 + HCl
If we can recall "Le Chatelier's Principle" states that if a certain pressure is exerted on a system the system will act as to relieve that pressure.
Case a. If we add NH4Cl to the system it means we have exerted a pressure on the right side of the equation and consequently the system will shift to the left to release ...
