Direction (Q. Nos. 9-18) This section contains 10 multiple choice questions. Each question has four choices (a), (b), (c) and (d), out of which ONE or MORE THAN ONE are correct. For in situ formation of Br2\text{Br}_2 , following reaction is used. 5Br−(aq)+BrO3−(aq)+6H+(aq)→3Br2(l)+3H2O(l)5\text{Br}^-(\text{aq}) + \text{BrO}_3^-(\text{aq}) + 6\text{H}^+(\text{aq}) \rightarrow 3\text{Br}_2(\text{l}) + 3\text{H}_2\text{O}(\text{l}) In this reaction, a. BrO3−\text{BrO}_3^- disproportionates to Br2\text{Br}_2 b. Br−\text{Br}^- disproportionates to Br2\text{Br}_2 c. Br−\text{Br}^- has been oxidised and BrO3−\text{BrO}_3^- has been reduced d. equivalent mass of Br2\text{Br}_2 is equal to its molar mass
