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.
