Given the equilibrium constants for the equilibria:
2H2O(l) → H3O+(aq) + OH-(aq); K = 1 x 10^-14
2CH3COOH(aq) + 2H2O(l) → 2CH3COO-(aq) + 2H3O+(aq); K = 3.6 x 10^-10
NH3(aq) + H2O(l) → OH-(aq) + NH4+(aq); K = 1.8 x 10^-5
Determine Kc for the following equilibrium: CH3COOH(aq) + NH3(aq) → CH3COO-(aq) + NH4+(aq)
How is the answer 3.1 x 10^4?
