A) \[2\]
B) \[0\]
C) \[3\]
D) \[1\]
Correct Answer: C
Solution :
\[A\xrightarrow{{}}B\] Rate \[=k{{[A]}^{n}}\] \[{{(Rate)}_{1}}=k{{(0.05)}^{n}}=2\times {{10}^{-3}}\] ?...(i) \[{{(Rate)}_{2}}=k{{(0.1)}^{n}}=1.6\times {{10}^{-2}}\] ??(ii) Dividing the Eq. (ii) by Eq. (i). \[\frac{{{(Rate)}_{2}}}{{{(Rate)}_{1}}}=\frac{k{{(0.1)}^{n}}}{k{{(0.05)}^{n}}}=\frac{1.6\times {{10}^{-2}}}{2\times {{10}^{-2}}}\] \[{{(2)}^{n}}=8\] or \[{{(2)}^{n}}={{2}^{3}}\] \[\therefore \] \[n=3\]You need to login to perform this action.
