A) decrease the \[{{H}^{+}}(aq)\] ion concentration
B) reduce HCN (aq) concentration
C) increase the equilibrium constant
D) decrease the equilibrium constant
Correct Answer: A
Solution :
For the reaction \[HCN(aq){{H}^{+}}(aq)+C{{N}^{-}}(aq)\] \[{{K}_{c}}=\frac{[{{H}^{+}}]\,\,[C{{N}^{-}}]}{[HCN]}\] On the addition of \[C{{N}^{-}}(aq)\] at equilibrium, the \[[{{H}^{+}}](aq)\] decrease to maintain the equilibrium constant.You need to login to perform this action.
