Explanation:We have to use the formula \\\\(W = \\frac E {96500} \ imes I \ imes t\\\\).Consider formation of chlorine molecule as shown below:\\\\(2Cl^- \\rightarrow Cl_2 + 2e^-\\\\)using formula,\\\\(0.1 \ imes 71\\\\) (Molecular mass of \\\\({Cl}_2\\\\)) \\\\(=\\frac {35.5}{96500} \ imes 3 \ imes t\\\\).\\\\(\ herefore\\\\) \\\\(t= 6433.33\\ seconds \\\\)\\\\(\ herefore\\\\) \\\\(t\\approx\\\\) \\\\(110\\ minutes\\\\)Final Answer: Hence option \\\\(D\\\\) is correct.
