For the following equilibrium: C2H2+2Br2⇌C2H2Br4 If the initial concentrations are: [C2H2]=0.25 M,[Br2]=0.50 M,[C2H2Br4]=2.5 M , and the reaction proceeds in the reverse direction until equilibration, where [ C2H2Br4]=2.15 M , what is the final concentration of Br2 ?
0.50
0.85
1.2
0.15
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
