From an initial mix of: 2 mol Cl2, 1 mol Br2, 1 mol I2, 1 mol Cl−, 1 mol Br−, & 5 mol I−; the total quantity of Br2 present after all possible reactions occur is
0 mol |
1 mol |
2 mol |
0.5 mol |
answer : 1 mole
only two possible reaction with Bromine
(1) Br2 +2 I - -------------------> 2Br- + I2
2 5 0 0 ---------------> initial
0 3 2 2-------------> after reaction
(2) Cl2 +2 Br- -----------------> 2Cl- + Br2
2 1 0 0
1 0 1 1---------------> after reaction
1 mol Br2 remaining after all reactions
