For the reaction Fe3+(aq) + SCN-(aq) Fe(SCN)2+(aq). a. Addition of SCN-(aq) will shift the equilibrium in favor of products. b. Addition of SCN-(aq) will shift the equilibrium in favor of reactants. c. Addition of Cl-(aq) will shift the equilibrium in favor of reactants.

Answer : The correct option is, (a) Addition of SCN⁻ (aq) will shift the equilibrium in favor of products.

Explanation :

The given reaction is:

Le-Chatelier's principle : This principle states that if any change in the variables of the reaction, the equilibrium will shift in the direction to minimize the effect.

Addition of SCN⁻ (aq)

If the concentration of is increased on reactant side then the equilibrium will shift in the direction where decrease of concentration of

Thus, the correct option is, (a) Addition of SCN⁻ (aq) will shift the equilibrium in favor of products.
