1.	The initial rate of reaction A+5B+6Cto3L+3M has been determined by measuring the rate of disappearance of A under the following conditions : {:("Expt. No.",,,[A]_(0)//M,,,[B]_(0)//M,,,[C]_(0)//M,,,"Initial rate"//"M min"^(-1)),(1,,,0.02,,,0.02,,,0.02,,,2.08xx10^(-3)),(2,,,0.01,,,0.02,,,0.02,,,1.04xx10^(-3)),(3,,,0.02,,,0.04,,,0.02,,,4.16xx10^(-3)),(4,,,0.02,,,0.02,,,0.04,,,8.32xx10^(-3)):} Determine the order of reaction with respect to each reactant and overall order of the reaction. What is the rate constant ? Calculate the initial rate of change in concentration of B and L.
Answer» Solution :Rare `(r_(0))=k[A_(0)]^(alpha)[B_(0)]^(beta)[C_(0)]^(LAMBDA)." Calculate "(r_(0))_(1)//(r_(0))_(2),(r_(0))_(3)//(r_(0))_(1),(r_(0))_(4)//(r_(0))_(1)` Initial rate `=-(1)/(5)(d[B])/(dt)=+(1)/(3)(d[L])/(dt)=2.08xx10^(-3)" M min"^(-1)"(Given)"` `:." Initial change in conc. of B, i.e., "(d[B])/(dt)=-5xx(2.08xx10^(-3))=-1.04xx10^(-2)" M min"^(-1)` Initial change in conc. of L, i.e., `(d[L])/(dt)=3xx(2.08xx10^(-3))=6.24xx10^(-3)" M min"^(-1)`
