A) \[2\]
B) \[1\]
C) \[3/2\]
D) \[4/3\]
Correct Answer: C
Solution :
\[A+B\xrightarrow{{}}C+D\] Rate \[(r)=k{{[A]}^{a}}\,{{[B]}^{b}}\] ??.(i) \[2r=k{{[2A]}^{a}}\,{{[B]}^{b}}\] ???(ii) \[3r=k{{[A]}^{a}}\,{{[9B]}^{b}}\] ??(iii) Dividing Eq. (ii) by Eq. (i) \[2={{2}^{a}}\] or \[a=1\] Dividing Eq. (iii) by Eq. (i) \[3={{9}^{b}}\] or \[3={{3}^{2b}}\] or \[2b=1\] or \[b=\frac{1}{2}\] So, order of reaction \[=1+\frac{1}{2}=\frac{3}{2}\] \[\Delta {{T}_{b}}=i.\,\,{{k}_{b}}.M\]You need to login to perform this action.
