Consider the conversion of benzene C₆H₆ to maleic acid HOOC-CH=CH-COOH at 298K according to the following reaction. 2C₆H₆ (l) + 9O₂ (g) + 4H₂O (l) → 2(HOOC-CH=CH-COOH) (s) + 4CO₂ (g) We would like to find out what is the reaction enthalpy, entropy and Gibbs free energy for the formation of maleic acid at 25oC and at 100oC in kJ/mol. Some useful information: HOOC-CH=CH-COOH (maleic acid) decomposes at 135oC, the boiling point of C₆H₆ (benzene) is 80.1oC, the molar heat capacity, Cp molar heat capacity of solid maleic acid reported as 135.6 J/(mol*K) at 294.4 K. The molar heat capacity of liquid benzene is 136 J/(mol*K), while the molar heat capacity of gaseous benzene is about 81.6 J/(mol·K) The molar heat capacity of liquid water is approximately 75.3 J/(mol*K) The molar heat capacity of water in the gas phase varies with temperature, but can be approximated with 33.5 J/(mol*K) The heat of vaporization ΔHvap of benzene is 30.77 kJ/mol at 80.1 °C (normal boiling point) and 33.9 kJ/mol at 25 °C (standard enthalpy of vaporization). Water has a heat of vaporization value of 40.65 kJ/mol at its boiling point of 100oC. Part A) Do you expect the entropy of this reaction at 298K to be positive, negative or around zero?
