A mixture consisting of 0.10 mol H₂(g) and 0.10 mol Br₂(g)is placed in a container of volume 2.0 L. The reaction H₂(g) 1 Br₂(g) → 2 HBr(g) is allowed to come to equilibrium. Then 0.20 mol HBr is placed into a second sealed container of volume 2.0 L at the same temperature and allowed to reach equilibrium with H₂ and Br₂.

Which of the following will be different in the two containers at equilibrium? Which will be the same?

(a) Amount of Br₂;

(b) Partial pressure of H₂;

(c) The ratio PHBr/PH₂PBr₂ ;

(d) The ratio PHBr/PBr₂;

(e) The ratio (PHBr)₂/PH₂PBr₂ ;

(f) The total pressure in the container. Explain each of your answers.
