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) S 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.
