The reaction below forms the molecule CHFClBr starting from atoms of the elements. C + H + F + Cl + Br → CHFClBr Given the change of energy of this reaction is ∆E= -1502 kJ and the average bond energies (in kJ/mol) C—H (413), C—Br (276), and C—Cl (328), what is the calculated value for the the C—F bond energy? Blank 1 kJ/mol Hint: (1) This question asks you to think about solving "backwards" from the way most of the other questions in this PiQ are phrased.
Homework Answers
Delta E(rxn) = 0 - [H(C-H) + H(C-Cl) + H(C-F) + H(C-Br)]
-1502 = -(413 + 328 + x + 276)
1502 = 1017 + x
x = 485 KJ/mol .... Answer

By using photons of specific wavelengths, chemists can dissociate gaseous HI to produce H atoms with accurately known speeds. When HI dissociates, the H atoms move away rapidly, whereas the relatively heavy I atoms move little. Use Table 9.2 in your textbook to answer the following questions: (a) What is the longest wavelength (in nm) that can dissociate a molecule of HI? 4.9) 406 nm (b) If a photon of 226 nm is used, what is the excess energy (in...
