What is the equilibrium constant for the reaction HCN(aq)+ OH^-(aq) →CN^-(aq)+ H₂O(l)

Question

Quizplus · Accepted Answer

The equilibrium constant for the reaction HCN(aq)+ OH^-(aq) →CN^-(aq)+ H₂O(l) is K_a/K_w. This is because the reaction is the conjugate acid-base reaction of the weak acid HCN and the weak base CN^-. The equilibrium constant for a conjugate acid-base reaction is equal to the ratio of the acid dissociation constant (K_a) of the acid to the water dissociation constant (K_w).
