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??
