Answer the following questions regarding the gaseous reaction of carbon monoxide and chlorine to create phosgene (COCI2): CO (g) + Cl2 (g) COCI2 (g) a) Without doing a calculation (i.e. using only the chemical reaction) do you expect the entropy change for this reaction to be positive or negative? From an entropic perspective, is this favorable or unfavorable? b) Calculate AS° at 298K for this reaction using the following thermodynamic data (AHº=-220 kJ.mol and and AG° =-206 kJ/mol c) Based on your calculation above, is this reaction always spontaneous, never spontaneous or sometimes spontaneous? If sometimes spontaneous, indicate whether this reaction is spontaneous at high or low temperatures. d) If this reaction is sometimes spontaneous, calculate the temperature at which the spontaneity of this reaction changes.
