A steel tank containing one mole of HCl(g) at 500 K is allowed to cool in a Miami, FL warehouse in December where the ambient temperature is 295 K. Calculate the change in the Helmholtz energy ΔA in kJ mol-1, for this process of attaining thermal equilibrium. The molar entropy Sm of HCl(g) over the aforementioned temperature range is given by Sm / (J K-1 mol-1) = 8.50 × 10-2T + 160 (Reminder: CV,m for HCl(g) is 36.2 J K-1...
