Predict whether the equilibrium for each reaction lies to left or right as written.

a. NH4+(aq) PO43-(aq) ? NH3(aq) + HPO42-(aq)

b. CH3COOH(aq) + CN-(aq) ?? CH3COO-(aq) + HCN(aq)

Solutions

Expert Solution

a.Ka for NH4⁺ =5.6 x 10-10

Ka for HPO4^2-=6.23 x 10-8
(Ka for HPO4^2->Ka for NH4⁺) so reaction favoured in left(reactants side)

b..Ka for CH3COOH =1.76 x 10-5

Ka for HCN=6.17 x 10-10

(Ka for CH3COOH>Ka for HCN so reaction favoured in right(product side)

Combining Equilibrium Constants. It is possible to predict the equilibrium constant of a reaction by combining two or more reactions for which the value of K is known. When combining equilibrium constants, it is important to note the following: When a reaction is reversed, its Kvalue is inverted; that is, Kreverse=1/Kforward. When the coefficients of a reaction are multiplied by a factor, the Kvalue is raised to the power of that factor. When reactions are added, their Kvalues are multiplied....
