Chapter 18, Problem 37QAP
Interpretation Introduction

Interpretation:

The century in which the boat was built should be determined.

Concept introduction:

Activity is defined as the product of rate constant and number of atoms. It is also defined as the rate of decay or expresses number of atoms decays in unit time.

The mathematical expression is given by:

A = kN

Where, A = activity, k = first order rate constant and N = number of radioactive nuclei.

Activity can be expressed in following units:

1 Bq = 1 atom/s

1 Ci = 3.700 × 1010 atoms/s

The relation between half-life and first order rate constant is given by:

k=0.693t1/2

Where, k = first order rate constant and t1/2 = half-life

The prediction of the age of organic material is based on the rate of decay of carbon-14. Carbon-14 is an isotope of carbon which is released in the atmosphere in the form of interaction of neutrons from cosmic radiation with ordinary nitrogen atoms.

The intake of radioactive carbon stops when plant or animal dies. The reaction is given as:

614C714N+10e

The half-life of radioactive decay of carbon-14 is 5730 years. The activity of sample is directly proportional to the amount of C-14. The mathematical expression is given by:

lnAoA=kt

Where, Ao = original activity

A = measured activity

t= age of the sample

Blurred answer

(a) Show that the lattice energies are inversely proportional to the distance between ions in MX (M = alkali metal, X = halide ions) by plotting the lattice energies of KF, KCl, and KI against the internuclear distances, dMX. The lattice energies of KF, KCl, and KI are 826, 717, and 645 kJ/mol, respectively. Does the correlation obtained correlate well? You will need to use a standard graphing program to construct the graph (such as a spreadsheet program). It will generate an equation for the line and calculate a correlation coefficient. (b) Estimate the lattice energy of KBr from your graph. (c) Find an experimental value for the lattice energy of KBr in the literature, and compare this value with the one calculated in (b). Do they agree?
Show the curved arrow mechanism and both products for the reaction between methyl iodide and propoxide. 1st attempt NV H 10: H H 1 Add the missing curved arrow notation. H + See Periodic Table
First I wanted to see if you would mind checking my graphs behind me. (They haven't been coming out right)? Second, could you help me explain if the rate of reaction is proportional to iodide and persulfate of each graph. I highlighted my answer and understanding but I'm not sure if I'm on the right track. Thank you in advance.
