Question

Chapter 6, Problem 6D.4E

Interpretation Introduction

Interpretation:

At what temperature will the rate of the given reaction be 10 percent greater that its rate at 25oC has to be found.

Concept Introduction:

Activation energy(Ea): The potential energy barrier that must be surmounted before reactants can be converted to products.

Arrhenius equation:

Arrhenius equation is a formula that represents the temperature dependence of reaction rates

The Arrhenius equation has to be represented as follows

K = Ae−Ea/RT

Ea represents the activation energy and it’s unit is kJ/mol

R represents the universal gas constant and it has the value of 8.314 J/K×mol

T represents the absolute temperature

A represents the frequency factor or collision frequency

Technetium is the first element in the periodic chart that does not have any stable isotopes. Technetium-99m is an especially interesting and valuable isotope as it emits a gamma ray with a half life ideally suited for medical tests. It would seem that the decay of technetium should fit the treatment above with the result In(c/c) = -kt. The table below includes data from the two sites: http://dailymed.nlm.nih.gov/dailymed/druginfo.cfm?id=7130 http://wiki.medpedia.com/Clinical: Neutrospec_(Technetium_(99m Tc)_fanolesomab). a. b. C. Graph the fraction (c/c.) on the vertical axis versus the time on the horizontal axis. Also graph In(c/c.) on the vertical axis versus time on the horizontal axis. When half of the original amount of starting material has hours fraction remaining disappeared, c/c = ½ and the equation In(c/c.) = -kt becomes In(0.5) = -kt1/2 where t₁₂ is the half life (the time for half of the material to decay away). Determine the slope of your In(c/c.) vs t graph and…
