At 400 K, the Equilibrium Constant for the Reaction Br₂

Multiple Choice

At 400 K, the equilibrium constant for the reaction Br₂ (g) + Cl₂ (g) 2BrCl (g)
Is K_p = 7.0. A closed vessel at 400 K is charged with 1.00 atm of Br₂ (g) , 1.00 atm of Cl₂ (g) , and 2.00 atm of BrCl (g) . Use Q to determine which of the statements below is true.

A) The equilibrium partial pressures of Br₂, Cl₂, and BrCl will be the same as the initial values.
B) The equilibrium partial pressure of Br₂ will be greater than 1.00 atm.
C) At equilibrium, the total pressure in the vessel will be less than the initial total pressure.
D) The equilibrium partial pressure of BrCl (g) will be greater than 2.00 atm.
E) The reaction will go to completion since there are equal amounts of Br₂ and Cl₂.
