Consider the reaction C6H5COOH(s) + (15/2) O2(g) → 7 CO2(g) + 3 H2O(l), for which the standard reaction enthalpy is ∆rHo = -3228.2 kJ. Calculate the ∆rUo for this reaction and determine whether any thermodynamic work would be done on (w > 0) or by (w < 0) the reaction system if the reaction is carried out at a constant pressure. (Assume that the gases in this reaction exhibit ideal-gas behavior at T = 298.15 K and P = 1 bar.)
