Lesser amounts were found in the other scenarios. The measurements, identification and quantification of phosgene in the decomposition product, were obtained through the use of gas chromatography, infrared spectroscopy ...
Cp° = A + B*t + C*t2+ D*t3+ E/t2. H° − H°298.15= A*t + B*t2/2 + C*t3/3 + D*t4/4 − E/t + F − H. S° = A*ln(t) + B*t + C*t2/2 + D*t3/3 − E/(2*t2) + G. Cp= heat capacity (J/mol*K) H° = standard enthalpy (kJ/mol) S° = standard entropy (J/mol*K) t = temperature (K) / 1000.
