2. For the following reactions, determine the equilibrium constants and whether the reactants or products are favored: a) HCOOH(aq) + H2O(l) → HCOO− (aq) + H3O + (aq) (To determine K, use [HCOOH] = 0.10 M and [HCOO− ] = [H3O + ] = 0.0042 M) b) H2CO3(aq) + ClO− (aq) → HCO3 − (aq) + HClO(aq) (To determine K, use Ka(H2CO3) = 4.3 × 10-7 and Ka(HClO) = 3.5 × 10-8 ) 3. For each of the above reactions...
