P6.36 We need to calculate a standard-state AĦ®, for the oxidation (C,H10) to terephthalic acid (TPA, C,O̟H), which is used in making plastic 2-L soda bottles. However, heats of formation of the compounds from the respective elements are not available. Reference tables do have information on heats for combustion to CO, (g) and H,O (1) at 25°C, and show that the energy released is 1089 kcal/mol for p-xylene (1) and 770 kcal/mol for TPA (s). C,H10 (1) + 3 O, (g) → C,0̟H, (s) +2 H,O (1) Determine a numerical value for Af r. Given that AÂ T, for CO, = -94 kcal/mol and AĦ, for liquid H,O = -68 kcal/mol, calculate AH¡ fr p-xylene and TPA. %3D

Question
P6.36 We need to calculate a standard-state AĦ", for the oxidation of p-xylene (CH1,) to terephthalic acid (TPA, C,O̟H), which is used in making plastic 2-L soda bottles. However, heats of formation of the compounds from the respective elements are not available. Reference tables do have information on heats for combustion to CO, (g) and H,O (1) at 25°C, and show that the energy released is 1089 kcal/mol for p-xylene (1) and 770 kcal/mol for TPA (s). C,H1, (1) + 3 O, (g) → C,0̟H, (s) +2 H,0 (1) -94 Determine a numerical value for AÊĤº. Given that AĤĦ; for CO2 kcal/mol and AĤ, for liquid H,O p-xylene and TPA. = -68 kcal/mol, calculate AH for
