ChemistrySingle correct+4 / -1Question 40 of 90

For the non - stoichiometre reaction $\ce{2A + B -> C + D}$ , the following kinetic data were obtained in three separate experiments, all at 298 K.

Initial Concentration (A)	Initial Concentration (B)	Initial rate of formation of C (mol L $^{-1}$ s $^{-1}$ )
0.1 M	0.1 M	$1.2\times10^{-3}$
0.1 M	0.2 M	$1.2\times10^{-3}$
0.2 M	0.1 M	$2.4\times10^{-3}$

The rate law for the formation of C is :

\dfrac{dc}{dt}=k[A][B]

\dfrac{dc}{dt}=k[A]^2[B]

\dfrac{dc}{dt}=k[A][B]^2

\dfrac{dc}{dt}=k[A]

Answer and worked solution

Official answer: D

So $\dfrac{dc}{dt}=k[A]$ .
