Find ΔErxn for the combustion of naphthalene. The heat capacity of the calorimeter, determined in a separate experiment, is 5.11kJ/∘C.
a.) The activity of a pure substance in the reference state is a = 1. With this in mind,
calculate the activity for liquid water at 25C for pressures of 10 bar and 100 bar,
assuming that the molar volume is constant. (4 credits)
b.) Consider two solutions whose solute activities are aB’ and aB”, referred to the
standard state. Show that the difference in the chemical potentials of these two
solutions is independent of the standard state and depends only on the ratio aB’/aB”.
c.) An aqueous solution of NaCl has a molality of 0.315 molkg-1. At what molality will
an aqueous solution of K2SO4 have the same ionic strength? (3 credits)
