Consider the following equilibrium for which DH = 29.28: Br2(g) + Cl2(g) ? 2 BrCl(g) How will each of the following changes affect an equilibrium mixture of the 3 gases in this reaction? (a) Cl2(g) is added to the system. (b) The reaction mixture is heated. (c) The volume of the reaction vessel is doubled. (d) A catalyst is added to the reaction mixture. (e) The total pressure of the system is increased by adding a noble gas. (f) BrCl(g) is removed from the system.
