4. Consider the following system at equilibrium: A+B C
a. According to Le Châtelier's Principle, what effect will increasing the
amount of reactant A have upon the amount of product C? Will it
increase the amount of C or decrease the amount of C?
b. In which direction did this increase in the amount of A shift the
equilibrium? To the left, or to the right?
