For the non-stoichiometric reaction 2A+B⟶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

This problem can be solved by determining the order of reaction with respect to each reactant and then writing rate law equation of the given equation accordingly as,R=dCdt=k[A]x[B]ywhere, x = order of reaction w.r.t  A            y = order of reaction w.r.t  B    1.2×10−3=k(0.1)x(0.1)y1.2×10−3=k(0.1)x(0.2)y2.4×10−3=k(0.2)x(0.1)yor     R=k[A]1[B]0
