At 400 K, the Equilibrium Constant for the Reaction Br₂

question 86

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.
