Interpretation:
Composition of LiCl/H2O solution at 250C formed adiabatically mixing cool water at 100C with a 20 mol% solution of LiCl/H2O at 250C should be calculated.
Concept Introduction:
Let us assume
Following three steps are associated with the preparation of final LiCl/H2O at 250C.
Enthalpy change for increasing water temperature from 100C to 250C. Let us assume this is denoted as
Enthalpy change for preparing 1 mol 20% solution of LiCl/H2O at 250C is to be calculated. This can be calculated from Figure 11.7 for plot of
Enthalpy change for mixing
Total heat effect in this entire process is denoted as
