Question #56724
From an initial mix of: 2 mol Cl2, 1 mol Br2, 0.5 mol I2, 0.5 mol Cl−, 1 mol Br−, & 2 mol I−; the total quantity of I2 present after all possible reactions occur is
Expert's answer
0.5 mol I2 and 0.5 mol Cl- will not react with anything;
2 mol I- will react with one mol of Cl2 producing one mol of I2:
2I- + Cl2 = I2 + 2Cl-
1 mol Br- will react with 0.5 mol of Cl2 producing 0.5 mol of Br2:
Br- + 0.5Cl2 = 0.5 Br2 + Cl-
Final mixture: 0.5 mol Cl2, 1.5 mol Br2, 1.5 mol I2, 3.5 mol Cl-
Quantity of I2: 1.5 mol
