For the overall reaction between A and B to yield C and D, two mechanisms are proposed: I. A+BtoAB*toC+D,k_(1)=1xx10^(-5)M^(-1)s^(-1) II. AtoA"*"toE,k_(1)=1xx10^(-4)s^(-1), E+BtoC+d,k_(2)=1xx10^(10)M^(-1)s^(-1) (species with * are short lived) AT what concetration of B, rates of two mechanism are equal?

Solution :`r_(1)=r_(2),K_(1)^(1)[A]^(1)[B]^(1)=K_(1)[A]^(1),[B]^(1)=(K_(1))/(K_(1)^(1))=(1XX10^(-4))/(1xx10^(-5))=10`
