A) \[-\frac{d\,[C]}{3\,dt}\]
B) \[-\frac{d\,[B]}{dt}\]
C) \[\frac{d\,[D]}{dt}\]
D) \[-\frac{d\,[A]}{2\,dt}\]
Correct Answer: A
Solution :
| [a] For the reaction 2A + B \[\to \] 3C + D |
| The reaction rate is written as follows: |
| The reaction rate w.r.t. \[A=-\frac{1}{2}\,\frac{d\,[A]}{dt}\] |
| The reaction rate w.r.t \[B=-\frac{d\,[B]}{dt}\] |
| The reaction rate w.r.t \[C=+\frac{1}{3}\,\frac{d\,[C]}{dt}\] |
| The reaction rate w.r.t \[D=\frac{d\,[D]}{dt}\] for product we take + sign because concentration of product increases with time |
| Hence, the answer is not correct expression to represent the rate of reaction. |
