Carbon disulfide 1CS22 is a toxic, highly flammable
Chapter , Problem 19.112(choose chapter or problem)
Carbon disulfide 1CS22 is a toxic, highly flammable substance. The following thermodynamic data are available for CS21l2 and CS21g2 at 298 K: (a) Draw the Lewis structure of the molecule. What do you predict for the bond order of the CS bonds? (b) Use the VSEPR method to predict the structure of the CS2 molecule. (c) Liquid CS2 burns in O2 with a blue flame, forming CO21g2 and SO21g2. Write a balanced equation for this reaction. (d) Using the data in the preceding table and in Appendix C, calculate H and G for the reaction in part (c). Is the reaction exothermic? Is it spontaneous at 298 K? (e) Use the data in the table to calculate S at 298 K for the vaporization of CS21l2. Is the sign of S as you would expect for a vaporization? (f) Using data in the table and your answer to part (e), estimate the boiling point of CS21l2. Do you predict that the substance will be a liquid or a gas at 298 K and 1 atm?
