| In the reaction, [AIPMT (S) 2009] |
| \[\frac{-d[{{H}_{2}}]}{dt}\] |
| \[3\times {{10}^{4}}\,mol\,{{L}^{-1}}\,{{s}^{-1}}\] |
| 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 :
| [a] 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 \[C{{H}_{2}}Br-C{{H}_{2}}-COBr\] |
| \[C{{H}_{3}}-\underset{\begin{smallmatrix} | \\ Br \end{smallmatrix}}{\overset{\begin{smallmatrix} Br \\ | \end{smallmatrix}}{\mathop{C}}}\,-COOH\] |
