Consider the reaction represented by the equation:

Fe3+(aq) + SCN-(aq) <====> FeSCN2+(aq) ddddd

§Trial #1:

6.00 M Fe3+(aq) and 10.0 M SCN-(aq) are mixed at a certain temperature and at equilibrium the concentration of FeSCN2+(aq) is 4.00 M.

What is the value for the equilibrium constant for this reaction?

k=0.333

§Trial #2:

Initial: 10.0 M Fe3+(aq) and 8.00 M SCN−(aq) (same temperature as Trial #1)

Equilibrium:    ?   M FeSCN2+(aq)

                      answer 5.00 M FeSCN2+

how can I solve trial #2??

An experiment with Le Chatelier's Principle resulted in this equation: Fe3+ + SCN- <=> Fe(SCN)2+ First off, should the first reactant be Fe2+ or Fe3+? Our TA said Fe2+, but I'm not sure why it's not Fe3+ since we were adding Fe3+ to observe changes in equilibrium. (The lab manual specifies that Fe(SCN)2+ in a product.) Second, it was obvious that adding Fe3+ and SCN- shifted the equilibrium to the right toward products. However, addition of NaH2PO4 shifted the equilibrium...
