You begin an experiment with 0.20 M reactant A and 0.40 M reactant B. After the reaction has been allowed to achieve equilibrium, you have 0.10 M product C. What molarity of A do you have remaining at equilibrium?
The balanced reaction is A + 2B <--> 2C
Choose one answer.
a. 0 M
b. 0.10 M
c. 0.15 M
d. 0.30 M
