Chapter 17, Problem 17B.11P
Interpretation Introduction

Interpretation:

The order of the reaction with respect to A and its rate constant has to be calculated for the composition of a liquid phase reaction 2AB.

Expert Solution & Answer
Check Mark

Explanation of Solution

The stoichiometry of the reaction relates product and reaction concentration as follows:

    [A]=[A]0-2[B]

When the reaction goes to completion, [B]=[A]0/2;hence[A]0=0.624moldm-3.  The half-life of A from its initial concentration is approximately 1200s, and that its half-life from the concentration at 1200sisalso1200s.  This indicates a first-order reaction.  From the graph given below it is confirmed that it is a first order reaction.

    ln[A]0[A]=kAt

Which follows from

d[A]dt=-kA[A]t/s0600120018002400[A]/(moldm-3)0.6240.4460.3180.2240.164[B]/(moldm-3)00.0890.1530.2000.230ln[A]0[A]00.340.671.021.34

Figure.1

The points lie on a straight line, which confirms first order kinetics.  Since the slope of the line is 5.6×10-4s-1kA=5.6×10-4s-1.  To express the rate law in the form

    v=-12d[A]dt=-(12)×(-kA[A])=12kA[A]k=12kA=2.8×10-4s-1

Interpreting NMR spectra is a skill that often requires some amount of practice, which, in turn, necessitates access to a collection of NMR spectra. Beyond Labz Organic Synthesis and Organic Qualitative Analysis have spectral libraries containing over 700 1H NMR spectra. In this assignment, you will take advantage of this by first predicting the NMR spectra for two closely related compounds and then checking your predictions by looking up the actual spectra in the spectra library. After completing this assignment, you may wish to select other compounds for additional practice. 1. Write the IUPAC names for the following two structures: Question 2 Question 3 2.
