Phosgene (COCl_2) has been used as a chemical agent in warfare. It blisters the lungs when breathed. Consider the following reaction:
CO(g) + Cl_2(g) --> COCl_2(g)

Important units:
CO: delta H = -110.5 kJ/mol and S = 197.6 J/mol*K
Cl_2: delta H = 0 kJ/mol and S = 223 J/mol*K
COCl_2: delta H = -223 kJ/mol and S = 289.2 J/mol*K

Calculate the temperature at which this reaction changes from spontaneous to non-spontaneous. Answer in units of K.
