Question

Br2(g) + Cl2(g) <=> 2BrCl(g)

is Keq = 7.0. A closed vessel at 400 K is charged with 1.00 atm ofBr2 (g), 1.00 atm of Cl2 (g), and 2.00 atm ofBrCl (g). Use Q to determine which of the statements below istrue.



a. The equilibrium partial pressuresof Br2, Cl2, and BrCl will be the same as theinitial values.

b. The equilibrium partialpressure of Br2 will be greater than 1.00atm.

c. At equilibrium, the total pressure inthe vessel will be less than the initial totalpressure.

d. The equilibrium partial pressure ofBrCl (g) will be greater than 2.00 atm.

e. The reaction will go to completionsince there are equal amounts of Br2 andCl2.
