Consider the reaction `HCN_((aq))hArrH_((aq))^(+) + CN_((aq))^(-)` . At equilibrium, the addition of `CN_((aq))^(-)` would

A

Reduce `HCN_((aq))` concentration

B

Decrease the `H_((aq))^(+)` ion consideration

C

Increase the equiliberium constant

D

Decrease the equilibrium constant

Text Solution

Verified by Experts

The correct Answer is:
B
At equilibrium, the addition addition of `(CN)^(-)` would decrease the `(H^(+))` ion concentration to prouduce more and more HCN to nullified the increse of `CN_(aq)^(-)` .
