Question

A. Consider the endothermic reaction at 25oC: FeSCN+2(aq) --><-- Fe+3(aq) + SCN-(aq)

What direction will the reaction shift in response to the following stresses? (Use arrows or write "right" , "left" , or "no shift"). 

a. More SCN- is added. 

b. Solid sodium hydroxide is added. (iron (III) hydroxide is insoluble).

c. The reaction container is set into ice water to cool.

d. The pressure of the air around the reaction is doubled.

e. Solid iron (III) chloride (FeCl3) is added.

B. At 25oC, Kc for thr above reaction is 9.1 x 10-6. Determine the equilibrium concentration of Fe+3 in the solution if 0.50 mol of FeSCN+2 is dissolved to make 2.50 liters of solution.
