Question

If you know that Delta H_R^o = 17 kJ mol^-1 and Delta G_R^o = 16.5 kJ mol^-1 for the following reaction: Ba(NO_3)_2(aq) + 2 KCl(aq) rightarrow BaCl_2(s) + 2 KNO_3(aq) Calculate the equilibrium constant K degree for the reaction. 100.0 mL of 0.0800 molar Ba(NO_3)_2 is mixed with 100.0 mL of 0.0600 molar KCI. How many grams of BaCl_2 precipitate? Calculate the equilibrium concentrations of Ba^+, K^+, NO_3^-, and Cl^- in the supernatant aqueous solution. Assume all activity coefficients equal 1.00.

Explanation / Answer

If you know that Delta H_R^o = 17 kJ mol^-1 and Delta G_R^o = 16.5 kJ mol^-1 for
