   For the non – stoichiometre reaction $2\mathrm{A}+\mathrm{B}\to \mathrm{C}+\mathrm{D}$, the following kinetic data were obtained in three separate experiments, all at $298\mathrm{K}$. | Initial Concentration (A) | Initial Concentration (B) | Initial rate of formation of C ($\mathrm{mol}{\mathrm{L}}^{-1}{\mathrm{s}}^{-1}$) | | :--- | :--- | :--- | | $0.1\mathrm{M}$ | $0.1\mathrm{M}$ | $1.2\times 10^{-3}$ | | $0.1\mathrm{M}$ | $0.2\mathrm{M}$ | $1.2\times 10^{-3}$ | | $0.2\mathrm{M}$ | $0.1\mathrm{M}$ | $2.4\times 10^{-3}$ | The rate law for the formation of C is:

   1. A.$\frac{dc}{dt}=k[A][B{]}^2$
   2. B.$\frac{dc}{dt}=k[A]$
   3. C.$\frac{dc}{dt}=k[A][B]$
   4. D.$\frac{dc}{dt}=k[A{]}^2[B]$
