From the following enthalpies of reaction,
4 HCl (g) + O2 (g) → 2 H2O (l) + 2 Cl2 (g) ∆H = -202.4 kJ/mol 1/2 H2 (g) + ½ F2 (g) → HF (l) ∆H = -600.0 kJ/mol H2 (g) + ½ O2 (g) → H2O (l) ∆H = -285.8 kJ/mol
Calculate ∆Hrxn for 2 HCl (g) + F2 (g) → 2 HF (l) + Cl2 (g) Just input a number.

Using a value of ksp = 1.8 x 10-2 for the reaction pbcl2 pb+2(aq) + 2cl -(aq). if the value of ksp was determined to be only 1.2 x 10-2: too much solid has dissolved. additional precipitate is forming. the solution is unsaturated. the ions are now combining to reduce their concentrations.
