Question

Eqiulibrium shift question?

Which of the following statements describes the behavior of the system if the partial pressure of bromine is reduced by 75% as equilibrium is established?

POBr will be consumed as equilibrium is established. is the answer, but my question is why.

The reaction system POBr3(g) POBr(g) + Br2(g) is at equilibrium.

Which of the following statements describes the behavior of the system if the partial pressure of bromine is reduced by 75% as equilibrium is established?

POBr will be consumed as equilibrium is established. is the answer, but my question is why.

Explanation / Answer

Is the answer "POBr3 will be consumed as equilibrium is established". This makes sense because as per Le Chatelier's Principle the equilibrium will shift in the direction so as to minimize the effect of the change. Here to compensate for the loss of bromine, more POBr3 will dissociate to produce more bromiine.
