18. (6 pts) For the reaction below at a certain temperature, it is found that the equilibrium concentrations in a 10 L rigid container are [H₂] = 3.0 M, [Br₂] = 1.5 M, and [HBr] = 2.5 M. H₂(g) + Br₂ (g) 2 HBr (g) If 15 moles of Br₂ are added to this equilibrium mixture (assume constant volume and temperature), what will be the concentration of Br₂ when equilibrium is re-established? a) 0.33 M b) 2.7 M c) 3.3 M d) 0.66 M e) 3.0 M
