Answer 1

Explanation:

Consider the following system under equilibrium:

Fe3+(aq)colorless+SCN−(aq)colorless⇌FeSCN2+(aq)red(15.8.1)(15.8.1)Fe3+(aq)⏟colorless+SCN−(aq)⏟colorless⇌FeSCN2+(aq)⏟red

If more Fe3+Fe3+ is added to the reaction, what will happen?

According to Le Chatelier's Principle, the system will react to minimize the stress. Since Fe3+ is on the reactant side of this reaction, the rate of the forward reaction will increase in order to "use up" the additional reactant. This will cause the equilibrium to shift to the right, producing more FeSCN2+. For this particular reaction, we will be able to see that this has happened, as the solution will become a darker red color.

There are a few different ways to state what happens here when more Fe3+ is added, all of which have the same meaning:

equilibrium shifts to the right

equilibrium shifts to the product side

the forward reaction is favored
