Le Chatelier’s principle states that “If you stress a system at equilibrium, the system will react to relieve the stress and return to equilibrium”. The following equation represents a chemical reaction at equilibrium:
2A (g) + 3B (g) <===> 2C (g) + 4D (g) ∆H = -378 kcal/mol (g) means gas
In each case below, explain how the system reacts (forward direction, reverse direction or no change):
The concentration of A is increased
Heat is added to the system
B is removed from the reaction
Pressure is added
The concentration of C is increased
