Question 1 ((9 + 9) + 7 = 25 marks) (a) Determine whether the reaction, CH3CH2CH2OH(1) + (9/2)O2(g) → 3CO2(g) + 4H2O(g), at 25 degrees Celsius, is spontaneous in an (i) isolated system and (ii) an open system. AH1°(CH3CH2CH2OH(1)) = -302.54 kJ mol-1; AHfº(CO2(g)) = -393.509 kJ mol-1; AHtº(H2O(g)) = -241.83 kJ mol-1 = AS°(CH3CH2CH2OH(1)) = 192.8 J K-1 mol-1; AS°(O2(g)) = 205.07 J K-1 mol-1; AS°(CO2(g)) = 213.74 J K-1 mol-1; = = = AS°(H2O(g)) = 188.84 J K-1 mol-1 (b) What is the difference between a closed system and an open system?
