Expert Solution

                                       C2H2+   2Br2    ⇌    C2H2Br4

      I                                 0.25       0.5           2.5

     C                              + 0.35      +2*0.35           -0.35

     E                                 0.6           1.2                   2.15

                           [Br2]   = 1.2M

The concentration of Br2   = 1.2M
