Q. For the reaction $ A+2B\xrightarrow[{}]{{}} $ Products, the differential rate equation is
Rajasthan PMT
Rajasthan PMT 2011
A
$ -\frac{1}{2}\frac{d[A]}{dt}=\frac{-d[B]}{dt}=k[A]{{[B]}^{2}} $
B
$ \frac{1}{2}-\frac{d[A]}{dt}=\frac{d[B]}{dt}=k[A]{{[B]}^{2}} $
C
$ \frac{-d[A]}{dt}=-\frac{1}{2}\frac{d[B]}{dt}=k[A]{{[B]}^{2}} $
D
$ \frac{d[A]}{dt}=\frac{1}{2}\frac{d[B]}{dt}=k[A]{{[B]}^{2}} $
Solution:
For the reaction $ A+2B\xrightarrow{{}} $ products The differential rate equation is Rate $ =\frac{-d[A]}{dt}=-\frac{1}{2}\frac{d[B]}{dt} $ $ =k[A][B]2 $ where, $ k= $ rate constant.
