QAIPMT-2009-Ch-2123: NEET 2009 Chemistry - Class 12 AIPMT-2009-Ch-2123 Solution: In the reaction, \(BrO_3^-(aq)+5Br^-(aq)+6H^+…

In the reaction, BrO3−(aq)+5Br−(aq)+6H+→3Br2(l)+3H2O(l)BrO_3^-(aq)+5Br^-(aq)+6H^+\rightarrow 3Br_2(l)+3H_2O(l). The rate of appearance of bromine (Br2Br_2) is related to rate of disappearance of bromide ions as

Multiple Choice Options

  • A d[Br2]dt=−53d[Br−]dt\frac{d[Br_2]}{dt}=-\frac{5}{3}\frac{d[Br^-]}{dt}
  • B d[Br2]dt=53d[Br−]dt\frac{d[Br_2]}{dt}=\frac{5}{3}\frac{d[Br^-]}{dt}
  • C d[Br2]dt=35d[Br−]dt\frac{d[Br_2]}{dt}=\frac{3}{5}\frac{d[Br^-]}{dt}
  • D d[Br2]dt=−35d[Br−]dt\frac{d[Br_2]}{dt}=-\frac{3}{5}\frac{d[Br^-]}{dt}

Step-by-Step Verified Solution

Rate = 1 3 d [ B r 2 ] d t = _ 1 5 d [ B r _ ] d t _ d [ B r 2 ] d t = _ 3 5 d [ B r _ ] d t
