An 8.00 g sample of SO3 was placed an evacuated container where it is decomposed at 600 degrees C according to the following reaction. SO3(g) <---> SO(g) + 1/2O2(g) At equilibrium the total pressure and density of the gaseous mixture were 1.80 atm and 1.60 g/L respectively. Calculate Kp for the reaction.
it is found that the equilibrium concentrations in a 5.00 L rigid container are [H2] = 0.0500 M, [F2] = 0.0100 M, and [HF] = 0.400 M. If 0.338 mol of F2 is added to this equilibrium mixture, calculate the concentrations of all gases once equilibri..
