A) unit of k must be \[{{s}^{-1}}\]
B) \[{{t}_{1/2}}\]is a constant
C) rate of formation of C is twice the rate of, disappearance of A
D) value of k is independent of the initial concentrations of A and B
Correct Answer: C
Solution :
\[2A+B\xrightarrow[{}]{{}}C\] Rate\[=k[A][B]\] It represents second-order reaction. Thus unit of k is \[{{M}^{-1}}{{s}^{-1}}\] \[\therefore \] is false \[{{T}_{50}}\]is dependent of concentration but not constant \[\therefore \](a) is false \[-\frac{1}{2}\frac{d[A]}{dt}=\frac{d[C]}{dt},\] thus (c) is correct
