For the non - stoichiometre reaction
2A + B → C + D, the following kinetic data were obtained in three separate experiments, all at $\displaystyle 298$ K.
The rate law for the formation of C is :
| Initial Concentration (A) | Initial Concentration (B) | Initial rate of formation of C $\displaystyle \left(\mathrm{mol} \mathrm{L}^{-} \mathrm{S}^{-}\right)$ |
| $\displaystyle 0.1$ M | $\displaystyle 0.1$ M | $\displaystyle 1.2 \times 10^{-3}$ |
| $\displaystyle 0.1$ M | $\displaystyle 0.2$ M | $\displaystyle 1.2 \times 10^{-3}$ |
| $\displaystyle 0.2$ M | $\displaystyle 0.1$ M | $\displaystyle 2.4 \times 10^{-3}$ |
Official answer
(4)
$\displaystyle \frac{\mathrm{dc}}{\mathrm{dt}}=\mathrm{k}[\mathrm{~A}]$
