Delta_Cp0: Heat Capacity of Solution per mole of salt (standard states)
|
|
rxn for the ss heat of soln: NaCl(s) -> Na+(aq) + Cl-(aq)
|
|
|
|
Delta_Cps: Delta heat Capacity of Solution per mole of salt
|
|
rxn for heat of soln: n1 H2O(l,pure) + n2 NaCl(s) -> n2 MX(aq) + n1 H2O(l)
|
|
Delta_Hs = (n1 h_H2O_bar + n2 h_MX_bar - n1 h_H2O_0 - n2 h_MX_0)/n2
