CHEMICAL ENERGY BALANCE - EXAMPLE 11.3 : For liquid benzene, the CP constants are : a = 129440, b = - 169.5, c = 0.64781. Reference temperature is 298 K. The temperature of benzene is 60 degree Celsius. Calculate the enthalpy of benzene by using the formula H = a (DT) + (b/2) (T^2 - TREF^2) + (c/3) (T^3 - TREF^3) where ^ is power, DT is temperature difference with TREF = 298 K. H is in J / kmol. DT = T - TREF.

Answer Posted / kangchuentat

CHEMICAL ENERGY BALANCE - ANSWER 11.3 : T = 60 + 273 = 333 K. H = 129440 (35) + (-169.5 / 2) (333^2 - 298^2) + (0.64781 / 3) (333^3 - 298^3) = 4917920 J / kmol.
