Question

The following data were obtained for initial reaction rates as a function of [A]0 and [B]0;

Initial Rate7.4*10-9Ms-15.92*10-8Ms-15.92*10-6Ms-1

Determine the order of this reaction with respect to both A and B, and obtain the rate constant for the reaction. After a drug enters the stomach, its concentration [B] in the blood grows by a first-order process with a rate constant k1, of 0.10 min-1 while at the same time it is degraded in the liver to a product C with a zero-order rate constant k0=3.0*10-4Mmin-1. The process an thus be represented by the reaction scheme A—k1à B---k0àC and the concentration [B] is given by the following integrated rate equation: [B] ={[A]0[1-exp9-k1t0]} – k0t, where [A]0 is a constant = 1.5*10-2M for a typical dose. You will need to write the equation for d[B]/dt according to the mechanism and then show that it is consistent with the above expression for [B] by obtaining the derivative an then calulate the time tmax and the corresponding [B]max at which [B] reaches its maximum value in order to estimate the time at which [B]is reduced to zero

Explanation / Answer

second order for a

The integrated rate law for a zeroth-order reaction also produces a straight line and has the general form

[A]=[A]0kt(14.16)

where [A]0 is the initial concentration of reactant A. (Equation 14.16 has the form of the algebraic equa
