On which side would the equilibrium lie for the following reaction? (Hint: Assign the species as acids/bases first!) NH₄+ + H₂PO₄ = H₃PO₄ + NH₃ pka= 9.8 7.2 2.2 33

a. To the left because the reactants are stronger acids and bases.

b. To the right because the reactants are stronger acids and bases.

c. To the right because the products are stronger acids and bases.

d. To the left because the products are stronger acids and bases.
