For the reaction HCN (aq)+ H₂O (l)$\leftrightarrow$ CN^- (aq)+ H₃O⁺ (aq),all of the following will shift the equilibrium toward the products,except: I adding HCN. II adding H₂O. III removing CN⁻. IV removing H₃O⁺.

Question

Quizplus · Accepted Answer

Adding H₂O does not shift the equilibrium toward the products because water is a solvent and its concentration is not considered in the equilibrium expression for this reaction.

For the Reaction HCN (Aq)+ H2O (L) ↔\leftrightarrow↔ CN- (Aq)+ H3O+ (Aq),all of the Following Will Shift the H3O+

For the Reaction HCN (Aq)+ H₂O (L) $\leftrightarrow$ CN^- (Aq)+ H₃O⁺ (Aq),all of the Following Will Shift the H₃O⁺
