The result given in the below table were obtained during kinetic studies of the following reaction 2A+B→C+DX and Y in the given table are respectively

Rate =k[A]a[B]bfrom Exp (1) and (2)  b=2from Exp (1) and (3) a=1from Exp (2) and (4) ⇒3=x0.11 so x=0.3from Exp (1) and (5) ⇒48=(3)1y0.12(4)2=y0.12 so y=0.4.
