12.19 mL of 0.1038 M KMnO4 were required to oxidize 25.00 mL of FeCl2. What is the molarity of the FeCl2, given the reaction: MnO4- (aq) + 5 Fe2+ (aq) + 8H+ (aq) ---> Mn2+ (aq) + 5Fe3+ (aq) + 4H2O (l)
0.01276 M
A + B ---> C
C ---> A + B
A + BC ---> AC + B

reversible reaction
reaction that proceeds simultaneously in both directions
the forward reaction and the reverse reaction proceed at equal rates
