Consider the following reaction: COCl2 (g) ⇌ CO (g) + Cl2 (g) A reaction mixture initially contains 1.6 M COCl2. Determine the equilibrium concentration of CO if Kc for the reaction at this temperature is 8.33 * 10-4 (Hint: Note the size of Kc).

Consider this equilibrium: N2 (g) + 2O2 (g) NO2 (g). Equal amounts of N2 and O2 are added, under certain conditions, to a closed container. Which changes occur in the reverse reaction as the system proceeds toward equilibrium? A.

Which form of energy is produced by an exothermic reaction?
