The compounds A and B form non-ideal solutions in the liquid phase. At 50 ?C, a mixture of A and B has an EXCESS molar enthalpy as given below:
The heat capacities of the liquids are modeled as constant. Both are equal to CP=50 J/mol-K.
In a steady-state, constant pressure process, 1000 mol/min of pure A at 25 ?C is mixed with 500 mol/min of pure B at 35 ?C. The mixture then enters a heat exchanger in which the mixture is heated to 50 ?C.
A. Determine the rate at which heat is added to the heat exchanger.
B. If we are using a reference state in which the molar enthalpy, ?H, of pure A and pure B are both 0 at a temperature of 25 ?C, then what is the partial molal enthalpy, ¯H, of compound A in the mixture that is leaving the heat exchanger?
