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

The rate law for the formation of C is

$\begin{array}{1 1}(A)\;\large\frac{dc}{dt}\normalsize= k[A][B]^2\\(B)\;\large\frac{dc}{dt}\normalsize= k[A]\\(C)\;\large\frac{dc}{dt}\normalsize= k[A][B]\\(D)\;\large\frac{dc}{dt}\normalsize= k[A]^2[B]\end{array}$

The rate law for the formation of C is $\large\frac{dc}{dt}\normalsize= k[A]$
Hence (B) is the correct answer.
