Much of the brown haze hanging over large cities is nitrogen dioxide, NO2(g). Nitrogen dioxide reacts to form dinitrogen tetroxide, N2O4(g), according to the equilibrium. 2NO2(g) N2O4(g) + 57.2 kJ (brown) (coulorless) Use this equilibrium to explain why t...

The Ksp of Ag2CrO4(s) is 1.12 x 10^-12. Calculate the molar solubility of AgCrO4(s) a)in pure water b) in a solution of 0.10 mol/L sodium chromate, Na2CrO4(s)

Given the equilibrium system PCL5(g) <----->PCl3(g) + Cl2(g) K = 12.5 at 60 degrees celsius. A 1.0 L reaction vessel is analyzed and found to contain 3.2 mol Cl2(g), 1.5 mol PCl3(g) and 2.0 mol PCl5(g). Show that the reaction mixture has not yet reached e...

The following reaction is used in the commercial production of hydrogen gas. CH4(g) + 2H2O(g) CO2(g) + 4H2(g) a) In a closed system how would a catalyst affect the establishment of equilibrium in the system? b) How would the concentration of H2(g) at equi...
