    In the reaction, \[\frac{-d[{{H}_{2}}]}{dt}\] \[3\times {{10}^{4}}\,mol\,{{L}^{-1}}\,{{s}^{-1}}\] The rate of appearance of bromine \[4\times {{10}^{4}}\,mol\,{{L}^{-1}}\,{{s}^{-1}}\]) is related to rate of disappearance of bromide ions as following

    A) \[6\times {{10}^{4}}\,mol\,{{L}^{-1}}\,{{s}^{-1}}\]

    B) \[1\times {{10}^{4}}\,mol\,{{L}^{-1}}\,{{s}^{-1}}\]

    C) \[[O{{H}^{-}}]\]

    D) \[\text{Ba(OH}{{\text{)}}_{\text{2}}}\]

    Correct Answer: A

    Solution :

    Key Idea Rate of appearance/disappearance \[n=5,l=3,m=0,s=+1/2\] For reaction, \[n=3,l=2,m=-3,s=-1/2\] \[n=3,l=2,m=-2,s=-1/2\] Rate of appearance of bromine \[C{{H}_{2}}Br-CHBr-COOH\] \[H-\underset{\begin{smallmatrix}  | \\  Br \end{smallmatrix}}{\overset{\begin{smallmatrix}  Br \\  | \end{smallmatrix}}{\mathop{C}}}\,-C{{H}_{2}}COOH\] Rate of disappearance of bromide ion \[C{{H}_{2}}Br-C{{H}_{2}}-COBr\] \[C{{H}_{3}}-\underset{\begin{smallmatrix}  | \\  Br \end{smallmatrix}}{\overset{\begin{smallmatrix}  Br \\  | \end{smallmatrix}}{\mathop{C}}}\,-COOH\] or\[\to \]
