Carbon disulfide (CS2) is a toxic, highly flammable substance. The following thermodynamic data are available for CS2(l) and CS2(g) at 298 K:


ΔHfo(kJ/mol) ΔGfo(kJ/mol)
CS2(I) 89.7 65.3
CS2(g) 117.4 67.2

(a) Draw the Lewis structure of the molecule. What do you predict for the bond order of the C - S 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 CO2(g) and SO2(g). 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 CS2(l). 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 CS2(l). Do you predict that the substance will be a liquid or a gas at 298 K and 1 atm?
