A) \[I,\,\,{{k}_{1}}/{{k}_{2}}\]
B) \[I,\,\,{{k}_{1}}\]
C) \[II,\,\,{{k}_{1}}/{{k}_{2}}\]
D) \[II,\,\,{{k}_{1}}/({{k}_{1}}+{{k}_{2}})\]
Correct Answer: B
Solution :
\[Rate=\frac{-d{{C}_{A}}}{dt}=\frac{{{k}_{1}}{{C}_{A}}}{1+{{k}_{2}}{{C}_{A}}}\] At very low \[{{C}_{A}},\,(1+{{k}_{2}}{{C}_{A}})\approx 1\] \[\therefore \,\, Rate={{k}_{1}}{{C}_{A}}\] \[\operatorname{Hence} order = I\] \[\operatorname{Rate}\,\,constant={{k}_{1}}\]You need to login to perform this action.
