For a reaction A+2B→C+DA + 2B \rightarrow C + D , the following data were obtained Expt. Initial concentration (moles litre −1^{-1} ) Initial Rate of formation of D (moles litre −1^{-1} min −1^{-1} )
[A][B]
1.0.10.16.0×10−36.0 \times 10^{-3}
2.0.30.27.2×10−27.2 \times 10^{-2}
3.0.30.42.88×10−12.88 \times 10^{-1}
4.0.40.12.4×10−22.4 \times 10^{-2}
The correct rate law expression will be :<br>&emsp;(A) Rate = k[A][B]k [A] [B]<br>&emsp;(B) Rate = k[A][B]2k [A] [B]^2<br>&emsp;(C) Rate = k[A]2[B]2k [A]^2 [B]^2<br>&emsp;(D) Rate = k[A]2[B]k [A]^2 [B]
