OThe combustion of acetylene is used in welder's torches because it produces a very hot flame: C,H;(g) + 0;(g) –→ 2CO;(g) + H;O(g) AH° = -1255.5 kJ (a) Use data in Appendix E to calculate AS for this reaction. (b) Calculate AG° and show that the reaction is sponta- neous at 25°C. (c) Is there any temperature range in which this reaction is not spontaneous? (d) Do you think you could use Equation 10.4 to calcu late such a temperature range reliably? Explain yo answer.

Draw the reactants and complete the mechanism by drawing in the appropriate electron-flow arrows (including stereochemistry) for the following Sy2 reaction of an alkyl bromide. Represent the nucleophile as an ion. Draw all missing reactants and/or products in the appropriate boxes by placing atoms on the grid and connecting them with bonds, including charges where needed. Indicate the mechanism by drawing the electron-flow arrows on the molecules. Arrows should start on an atom or a bond and should end on an atom, bond, or where a new bond should be created. • View Available Hint(s) + CH N H. S CH H,C C-ÖH CI HC Br HC F [1] A
