A) 1.5
B) 2.0
C) 2.5
D) 3.0
Correct Answer: B
Solution :
[b] 2.0 Rate \[(r)=k\,{{[A]}^{\alpha }}\] \[\therefore \,\,2.4=k\times {{(202)}^{\alpha }}\] On reducing the concentration of half i.e., when [A] = 1.1 m M, rate = \[0.6\text{ }m\text{ }M{{s}^{-1}}\] Hence, \[0.6=k\,{{(1.1)}^{\alpha }}\] Dividing (i) by (ii) \[4=2{}^\circ \] \[\therefore \alpha =2\]You need to login to perform this action.
