Question

Consider the following reactions at 298K.

2H2O(l) Û OH¯(aq) + H3O+(aq) K = 1.0 x 10-14
HF(aq) + H2O(l) Û F¯(aq) + H3O+(aq) K = 6.8 x 10-4

a. Write the equilibrium constant expression for the second reaction.

b. Calculate the value of the equilibrium constant for the following reaction at 298K.
F¯(aq) + H3O+(aq) Û HF(aq) + H2O(l)
K =

c. Calculate the value of the equilibrium constant for the following reaction at 298K.
F¯(aq) + H2O(l) Û HF(aq) + OH¯(aq)
K=
