A) POBr will be consumed as equilibrium is established.
B) The partial pressure of POBr will decrease while the partial pressure of Br₂ increases as equilibrium is established.
C) POBr₃ will be consumed as equilibrium is established.
D) The volume will have to decrease before equilibrium can be reestablished.
E) Bromine will be generated as equilibrium is established.
