In the industrial process of ammonia synthesis, it is separated from the other gases present in the reactor by means of liquefaction via cooling. Calculate the amount of heat at constant pressure that must be removed per mole of ammonia if the gas leaving the reactor at 650 K is cooled isobarically to 253 K.

DICE: Enthalpy of vaporization = 23.4 kJ/mol, at Vaporization Temperature = 239 K Cp[liquid,J/(K.mol)] = 81 Cp[gas,J/(K.mol)]= A + B*T + C / T A = 29.75, B = 0.0251, C = -16x10

Give your answer as a positive number in kJ/mol and round to a whole number.
