A) 0
B) 1
C) 2
D) 3
Correct Answer: C
Solution :
[c] Rate \[(r)=k{{[A]}^{n}}=k{{(X)}^{n}}\] \[6.25\times r=k\,{{(2.5X)}^{n}}\] or \[6.25\times k\times {{(X)}^{n}}=k{{(2.5\times X)}^{n}}\] \[\Rightarrow \,\,\,\,\left( \frac{2.5X}{X} \right)=6.25\Rightarrow {{(2.5)}^{n}}={{(2.5)}^{2}}\] \[\therefore \,\,\,n=2\]You need to login to perform this action.
