Example

Problem: For the following chemical reaction: Br 2(g) + Cl2(g) ⇌ 2BrCl(g) At 400 K, the equilibrium constant is K p = 7.0. A closed vessel at 400 K is filled with 1.00 atm of Br2(g), 1.00 atm of Cl2(g), and 2.00 atm of BrCl(g). Use Q p to determine which of the statements below is true. A) At equilibrium, the total pressure in the vessel will be less than the initial total pressure. B) The equilibrium partial pressure of Br 2(g) will be greater than 1.00 atm. C) The reaction will go to completion. D) The equilibrium partial pressure of BrCl(g) will be greater than 2.00 atm. E) The reaction shifts to the left
